FTIR Accessories Overview 

Selection of Optional Accessories 

Shimadzu's FTIR instruments have simple optics to give an 

attachment having complicated optics its full play. In FTIR, which 

ensures exceptionally high wavenumber accuracy, even a singlebeam 

instrument provides satisfactory spectra, which means that the 

reference sample and the unknown sample can be measured 

individually; the net result is that, in FTIR, only one piece of 

attachment or accessory is useful enough. In dispersive IR, by 

contrast, attachments and accessories must be used as a pair. This 

is a great advantage from an economic viewpoint. 

Most of the attachments and accessories are designed so that 

samples may be measured without preparation. 

Shown to the right is a flow chart for selecting attachments and 

accessories. The results of FTIR analysis depend greatly 

on the type of attachment and accessory used in analysis.

Attenuated Total Reflection Method 

The Attenuated Total Reflection (ATR) method, also called Multiple Internal Reflectance (MIR) method, is a versatile and powerful technique 

for infrared absorption spectrophotometry. This method is popular not only in FTIR but also in conventional dispersive IR, because it is not 

necessary to chemically treat, or machine, the samples. Measurement is made without destroying the samples. 

FTIR instruments, which ensure far higher sensitivity than dispersive lR instruments, dramatically widen the scope of application scope of the 

attenuated total reflection method; hence, a wide variety of attachments have been developed for this application. 

Shimadzu also provides a variety of ATR attachments. 

Principle 

The sample is held in contact with a prism made of highly refractive 

material, which transmits infrared rays; infrared rays are made 

incident on this sample at an angle larger than the critical angle 

(angle that induces total reflection). The light that is totally reflected 

by the interface between the sample and the prism is measured to 

obtain an infrared spectrum. 

Though it is called "total reflection", the light travels through the thin 

surface layer of the sample, as shown in the figure below, and 

therefore, the spectrum obtained is similar to that obtained from a 

very thin slice of the same sample. 

Requirements for Measurements by the ATR Method 

The sample must be placed in close contact 

with the surface of the prism. 

The prism has a higher refractive index 

than the sample. 

Penetration Depth of IR Light (Sample thickness) 

Infrared light can penetrate 

to a depth expressed 

by the next equation:

When θ= 45° and n21 = 0.5, therefore, 10μm (1000 cm-1) dp 

corresponds to 3.18μm and 5μm dp (2000 cm-1 ) to 1.6μm. 

The ATR method provides spectra of surface layers without actually 

slicing them. 

Since the measurable depth (thickness) differs with the wavelength 

of the light, the ATR method give spectra of a little different shape 

though the peak wavenumbers are the same. 

The software program for correcting for penetration depth, 

incorporated in the IRPrestige-21, IRAffinity-1, FTIR-8000 Series 

further widens the application field of the ATR method.

ATR-8000A (P/N 206-62303-91) 

ATR-8000 (P/N 206-62303) 

In the ATR-8000 series, the incident angle is changeable in three 

steps of 30°, 45°, and 60°, so that measurement can be made to 

different depths. Combined with the program to correct for the 

penetrating depth of the infrared rays (which is a weak point of the 

ATR method because it differs depending on the wavenumber), this 

feature provides spectra that are highly comparable to those given by 

another method. QuickStart ATR-8000A includes the automatic 

accessory recognition function. 

Features 

It is not necessary to adjust the position of the prism when a new 

sample is set. 

The sample holder is held at one point; hence, the prism is under 

minimized force. 

45 times reflection (with an incident angle of 45°) ensures high 

sensitivity. 

Standard software includes a program to correct for penetration 

depth. 

Maximum sample size: 40mm x 15mm, 10mm thick

measured. QuickStart ATR-8200HA includes the automatic 

accessory recognition function. 

Features 

Prisms for liquid samples and for solid samples are provided as 

standard. 

The prism is mounted and dismounted by one-touch operation, 

which ensures easy exchange of samples. 

ZnSe prisms are very chemically stable and ensure high 

mechanical strength.

The prism for solid samples permits easy measurement of film type 

and other solid samples, the operation being the same as that for the 

ATR-8000. 

A plate is fixed with screws to put the sample in close contact with 

the prism surface, which ensures high reliability of the spectra. 

Spectrum of PVDC Sheet 

The prism for solid samples permits easy measurement of film and other solid samples, with 

operation being the same as that for the regular ATR. 

A gripper is fixed to hold the sample in close contact with the prism surface, which enables highly 

reliable spectra.

DuraSamplIR2 (Diamond ATR) 

This is a single-reflection ATR system that presses an approximately 

2 mm diameter diamond prism tightly against the sample. The 

diamond prism allows the analysis of hard samples. The fit between 

the sample and prism is extremely good, making it convenient for 

liquids, solids, powders, fibers and film samples. With System I 

(High-Pressure Device type), the sample is pressed tightly against 

the prism by the clamper accessory while adjusting the clamping 

pressure. With System H (ViewIR type), the sample can be observed 

as it is being clamped. System I is also available with a pressure 

sensor included. 

ZnSe and KRS-5 support elements are available to support the 

diamond prism. The measurement wavenumber range is up to 650 

cm-1 for ZnSe and 400 cm-1 for KRS-5. 

The pressure sensor cannot be added later. If it will be needed, 

please include it when purchasing the system.

DuraScope (P/N 208-92184) 

As with the DuraSamplIR, this is a single-reflection diamond ATR, 

where measurements are conducted by pressing the sample against 

the approximately 2 mm diameter diamond prism. A micro CCD 

camera is provided directly below the diamond prism to allow the 

observation of the contact status between the sample and prism on a 

video monitor. The built-in pressure sensor indicates the pressure 

being applied to the prism. Apart from solid samples such as plastics, 

film or powders, liquid samples can be also analyzed by being 

dropped onto the prism surface.

method. 

IR rays 

This method has recently come to be applied to the measurement of 

very thin (a few tens of angstroms thick) samples, e.g. organic LB 

films (Langmuir-Brodgett's Iayers), and to the determination of 

molecular orientation. 

When a polarized Iight beam is made incident on a metal substrate, 

as shown below, it is changed in phase when reflected by the metal 

surface. 

1. In vertical polarization, the vectors of the polarized light are 

opposite to each other. Therefore, no stationary waves are 

produced on the substrate, and interaction with the film material is 

not detected. 

2. ln parallel polarization, the vectors of the polarized Iight meet at a 

point to produce stationary waves, which interact with the film and 

are absorbed. The intensity of this absorption is dependent on the 

incident angle: the larger the incident angle, the higher the 

intensity of absorption. The optimum incident angle is different 

with the type of sample and the wavelength of the peak under

2.Conversion of Reflection Spectra into Absorption Spectra 

A reflection spectrum, which provides information on the optical 

properties of the sample, must be converted into the absorption 

spectrum to be informative about the chemical structure of the 

sample. The Kramers-Kronig analysis method is quite convenient in 

that it is useful to convert a reflection spectrum into an absorption 

spectrum: it is not necessary to shave or slice the sample. In the 

example (2) shown below, when the ø is sufficiently small, each 

element of the complex refractive index of a material may be 

expressed as: 

1-R 

Reflectance value n= (1) 

1+R-2√Rcosθ 

Absorption coefficient 

-2√Rsinθ 

k= 1+R-2√Rcosθ 

Examples of Applications 

(2) 

where, R: Reflectance value 

θ: phase shift when the light is reflected. 

The θ for the wavenumber vg may be calculated from the following 

Kramers-Kronig equation: 

θ(νg)= dν 

ν2−νg2 2νg ∞ 

In√R(ν) 

π ∫ 0 

The θ can be obtained from the reflectance value R, and substituting 

that θ in the equation (2) gives the absorption coefficient k. 

Performing this calculation for all the wavenumbers will give the 

absorption spectrum. 

Since a reflection spectrum can be converted into the absorption spectrum through Kramers-Kronig analysis, 

1Absorption spectrum can be obtained without shaving or slicing the sample, provided that the sample has a smooth surface. lt is not 

necessary to use an ATR prism or a costly attachment. 

2Kramers-Kronig analysis method is especially effective for infrared microscopy, where it is virtually impossible to slice the sample.

RAS-8000 (P/N 206-62302) 

The reflection absorption spectrometry method is used only in FTIR. 

When a vertically polarized light and a horizontally polarized light are 

made incident on a metal substrate, the lights are changed in the 

respective phase. 

In the case of vertically polarized light, the phase change 

is about π, 

irrespective of the incident angle, and, hence, 

the vectors of the reflected light interact destructively with 

each other; the stationary waves produced have almost 

zero amplitude - no absorption of the sample is detected. 

In the case of horizontally polarized light, the amount of 

phase change varies continuously from zero (for 0° incident angle) to 

π 

(for 90°). The amplitude of the stationary waves produced also 

changes with the incident angle: when a high incident angle is 

selected, the stationary waves will have a high amplitude and the 

interaction of the light beam and the sample will be high, resulting in 

a high detecting sensitivity. This method permits high-sensitivity 

measurement of thin films on metals having a high reflectance. 

Combined use of a grid polarizer further enhances the sensitivity. 

A grid polarizer (P/N 206-61550) is not included in the standard 

content of the RAS-8000 series but is available as an option. 

QuickStart RAS-8000A includes the automatic accessory recognition 

function.

Diffuse Reflectance Spectroscopy 

In measurement of powder samples by the dispersive IR method, the 

KBr pellet method is often used. The powder sample is mixed with 

alkali halide powder, such as KBr, and briquetted into a pellet, which 

is then measured by the transmission method. This KBr pellet 

method is also used in FTIR, but the diffuse reflection spectroscopic 

method is easier to perform. 

As shown in the figure below, when a light beam is made incident on 

a powder sample, some part of the light is specularly reflected by the 

surface of the powder. The other part penetrates into the sample and 

is transmitted and reflected repeatedly, and then emerges out of the 

sample as a diffuse reflected (scattered) light. This diffuse reflected 

light is informative of the IR spectrum of the powder sample.

Applications 

Specularly

Reflection Within Powder Sample 

Incident light 

The diffuse reflectance spectroscopic method is applicable to any 

sample that can be pulverized. It also permits using, as the diluting 

substance, diamond powder or the like, which is not applicable to the 

KBr pellet method. 

This method is also applicable to detection of substances dissolved 

in a volatile solvent, such as fractions of liquid chromatography. LC 

effluent is made to drop on KBr powder, the mobile phase is 

removed by evaporation, and then the fraction is analyzed with the 

FTIR instrument equipped with a diffuse reflectance attachment. 

Diffuse reflected light, which has been repeatedly transmitted within 

the powder sample, gives a spectrum similar to ordinary transmission 

spectrum. The spectral intensity is not completely proportional to the 

concentration of the compounds under study: those components 

which are detected as rather low intensity absorption bands are 

detected at higher intensity because the light beam is transmitted 

repeatedly in the sample. It is necessary, therefore, to compare 

diffuse reflected spectra with ordinary transmission spectra or to 

convert them with the Kubelka-Munk equation. 

f= (1-R) 2 /2R = K/S 

where, K: absorption coefficient 

S: scattering coefficient 

R: reflection index 

(sample power spectrum/dilution power spectrum) 

Since it is very difficult to measure absolute reflection indices, diffuse 

reflection indices, which are the values relative to the reflection of 

KBr or KCI powder having no absorption in the IR region, are 

generally used. 

The spectra thus obtained are Kubelka-Munk converted to have 

intensities proportional to concentration. The result is spectra useful 

for quantitative determination. The FTIR-8000 Series / IRPrestige-21 

incorporates the Kubelka-Munk conversion function as a standard 

feature.

Measurement of Micro Samples 

FTIR ensures such a high sensitivity as to 

permit reliable measurement of micro 

samples. 

There are two popular devices to measure 

micro samples: beam condenser and infrared 

microscope. The objects of measurement are 

classified as the selected small part of the 

sample and a small part of a sample of 

uniform composition; measurement is made in 

either the reflection mode or transmission 

mode. These may be tabulated as follows: 

Transmission mode 

As shown in the figures, both in the beam condenser and the IR microscope, the 

IR light beam from the interferometer is condensed by the optics and made 

incident on the sample. The light beam from the sample is expanded to the original 

size and condensed on the detector, and then measured with the detector. 

The measurement principle of measurement is the same as that of ordinary 

samples, but in the case of micro samples, it is important to take the sample 

thickness into due consideration. 

In measurement of 50 μm thick yarn samples, for example, if measurement is 

made without reducing the thickness, the detector signal will be saturated-resulting 

in deformed absorption bands. It is necessary to compress the sample using a 

diamond cell or the like. 

Ordinary glass lenses are used for visual observation, while reflection mirrors must 

be used for lR measurement. 

Reflection mode 

Infrared microscopy is effectively used in reflection mode. As shown in the figure, 

the IR light from the interferometer is condensed by the reflecting objective and 

made incident on the sample, and the reflected light travels back to the same 

objective to be sensed by the detector. The paths for the incident light beam and 

the reflected light beam are switched by the wedge mirror. 

Though the measurement principle is the same as that of the samples of ordinary 

sizes, since the measurement is made on a very small area, specular reflection 

often occurs, resulting in abnormal peaks. The optics for visual observation and for 

lR rays are the same as that for the transmission mode.

The Attenuated Total Reflection (ATR) method is effectively used for 

samples that are opaque to IR rays, as well as for IR microscopy. It 

is especially effective for analysis of foreign materials on the resin 

surface and measurement of samples with curved surfaces. 

As shown in the figure, a semicircular prism is placed at the focus of 

the reflecting objective, and the light totally reflected by the interface 

of the sample and prism is measured to obtain the IR spectrum.

to a variety of samples including drugs, rubber and plastic. 

Two types of cells are available, Diamond Cell C using an artificial 

diamond and Diamond Cell B using a natural diamond. 

Notes • Diamonds exhibit slight absorption in the range 3,000 to 1,500 cm -1 . 

• Diamonds are hard but brittle and may crack depending on the 

sample and method of use. 

Diamond Cell C (P/N 208-92236) 

A pressurized cell-enabling microscopic measurement of minute, thinly 

compressed samples as they are. Applicable for analysis of drugs, rubbers, 

plastics, polymers, etc. 

The Diamond Cell B noted above employs a natural diamond, and is 

therefore relatively expensive. This Diamond Cell, on the other hand, uses 

an artificial diamond, so is less expensive and, further, employs a thinner 

and larger diameter window (1.6 mm). Although its strength is slightly inferior 

to the natural diamond, it is adequate for compressing nearly all samples. 

Features 

Large-size diamond provides 1.6mm diameter window 

Large diameter window allows measurement even when placed in 

standard sample compartment 

Measurement possible by merely placing on infrared microscope stage

Case 


Diamond Cell B (P/N 200-66752) 

This attachment is used to compress a micro sample into a thin plate, 

which is then directly measured by infrared microscopy. 

This method is applicable to various types of samples, such as 

pharmaceuticals, rubbers, plastics, and polymers. 

Features 

Use of the Type II diamond cell allows measurement to be made over 

the entire wavenumber range. 

Even thick samples can be measured in the transmission mode, with a 

high sensitivity. 

Micro samples are made flat, so that high sensitivity is obtained during 

measurement. 

Measurement is made with the diamond cell placed on the stage as it is. 

Adjustment for sample thickness is made with a precision screw. 

Cells with a cell plate of lower-cost material are also applicable. 

Combined use with an infrared microscope is recommended.

Accessories for Automated Measurement 

Automating the Operation 

The technique of Fourier Transform Infrared Spectrophotometry (FTIR) 

is now extensively used in various fields for R&D and industrial 

purposes. 

Since samples measured by infrared spectrophotometry are mostly 

chemically stable and can be measured without pretreatment, it is fairly 

easy to automate the measurement of many samples. 

Automating the measurement saves labor and ensures high analytical 

productivity. 

Automating the FTIR Measurement 

One of the most important methods to automate the operation of the 

FTIR main is to utilize a computer system. 

Combination of a computer and the program, described below, provides 

automation of sample loading and unloading, measurement, data 

processing, and presentation of the analytical results. 

The photo to the right shows the ASC connector (supplied as standard), 

which is used to export the control signals to an automatic sample 

changer. The software incorporated in the FTIR can control the 

automatic sample changer via a pair of the ASC connectors. 

Operation by Automated Sequence 

The operation must be carried out in the sequence programmed to be 

most appropriate for the particular type of samples under study. 

The Shimadzu FTIR-8000 Series instruments (except FTIR-8000PC 

Series) incorporate, as standard, the SPECTROMACRO software, 

which permits flexible programming through simple procedures. 

As for the FTIR-8000PC Series, the optional BASIC software has the 

same functions as SPECTROMACRO. 

IRPrestige-21, IRAffinity-1 and FTIR-8400S (IRsolution model) can be 

controlled from the IRsolution software. 

ASC Connector


DRS-8010ASC (P/N 206-62308) 

This attachment automates measurement of up to 24 samples. 

For details, refer to page 19. 

Notes 

When this attachment is used on IRAffinity-1, the ASC cable (P/N 206-73433-91) is required. 

The BASIC software is required separately for the HYPER-IR model. 

Auto Sampler for Transmission Measurement 

ASC-8000T (P/N 206-63900) 

This attachment accepts up to 18 samples for measurement in the 

transmission mode. 

Features 

The control is made by the standard control signals from the FTIR 

main, meaning no external controller is required. 

The attachment is easily installed in the standard sample compartment. 

A holder for a 13 mm dia. pellet is provided. 

Use of the window-plate option enables measurement in the Nujol method.

The FTIR Series uses a sealed interferometer to ensure high 

sensitivity and stability during measurement without using dry air. To 

eliminate the interference of carbon dioxide and water vapor, it is 

recommended to purge the interferometer, the sample compartment, 

the second sample compartment, etc. through a combined use of the 

purge control unit and the dry air supply unit or nitrogen gas. 

This kit is for adjusting the piping between the FTIR and purge gas 

source, piping sections along which purge gas flows and the purge 

gas flow rate. 

This kit contains the following parts: 

Flow path and flow rate controller 

Purge tube (10 m, 7 mm I.D., 10 mm O.D.) 

Exhaust parts

Second Sample Compartment (with MCT detector) 

SSU-8000MCT (P/N 206-62306-01) 

(Not applicable to FTIR-8101) 

If a gas cell, a flow cell, a thermovac evaporation type diffuse 

reflectance attachment, or another attachment that is to be installed 

externally is mounted to, and removed from, the standard sample 

compartment, high analytical productivity cannot be expected. The 

second sample compartment is used to accept such an attachment, 

so that measurement can be made by only switching the light beam. 

This method dramatically enhances analytical productivity. 

Also, the second sample compartment is designed to accept a 

customer-developed attachment. 

Features 

The base plate of the FTIR main body is removed and the SSU- 

8000MCT is installed in that place. 

The front panel and the top lid may be separately opened. The 

front panel may be removed by one-touch operation. 

A part (an acrylic resin plate) of the top lid may be removed. 

Equipped with piping for purge gas (dry air or nitrogen). 

For the type that accepts both the second compartment and the 

infrared microscope, please contact us or your local distributor. 

The MCT-8000 detector (supplied as standard) provides extremely 

high sensitivity and covers a wavenumber region of 4600 cm-1 to 

750 cm-1 . 

The glass dewar type MCT detector requires no reevacuation.

Accessories for Transmission Measurement 

Film samples can be measured easily if they are attached to the 

standard cassette or optional film holder. 

Cassette (Sample Holder) (P/N 206-17384) 

A cassette (sample holder) provided as standard on the FTIR can be 

used for options for attaching to cassettes for liquid and gas cells. 

However, with some accessories, there may be clearance between 

the cell and the cassette, which sometimes results in poor 

attachment reproducibility. 

Also, bending sometimes occurs when heavy accessories such as 

the 10 cm gas cell are attached. Use this optional cassette when 

performing measurement with such accessories with better 

reproducibility. 

This attachment cannot be used on the FTIR-8100/8100M/8100A/ 

8200/8200D/8200A/8500/8600 and FTIR-8200PC/8600PC.

Measurement Using 

Demountable Cells 

Demountable cells, sealed liquid cells, fixed thickness cells, etc. are 

useful for measurement of liquid samples. In quantitative analyses, it 

is necessary to know the thickness of the cell accurately. 

Interference patterns are often used for the thickness measurement. 

In transmission/reflection FTIR of thin films, an interference pattern 

as shown above is overlaid on the spectrum. The film thickness, t, is 

given by the next equation: 

M 

n= 2√n 2 -sin 2 θ(ν1-ν2) 

where ν1 and ν2 are the wavelengths of peaks or valleys, M is the 

degree of interference (number of the waves) between ν1 and ν2. 

When the refractive index (n) of the film is known and is uniform

Far Infrared Kit (P/N 206-72016-91) 

In the far infrared region up to 240 cm-1, peaks of inorganic 

compounds and organometallic complexes are observed. The Far 

Infrared Kit is a Csl beam splitter mounted on the IRPrestige-21 for 

measuring spectra in the far infrared region. Using the Csl beam 

splitter enables spectra in the far infrared region up to 240 cm-1 to be 

measured. 

A standard light source and detector are used. 

Since the 400 cm-1 to 240 cm-1 region absorbs lots of moisture in air, 

purge the instrument with desiccated air, for example, before 

performing measurement. Also, store the Csl beam splitter in a 

desiccator when it is not in use since it is extremely sensitive to 

moisture.

NIR Measurement Accessories for 

the IRPrestige-21 

Accessories are available for easier and higher-sensitivity NIR 

measurement of a wide range of samples. Each accessory is 

equipped with the Automatic Accessory Recognition function. 

Introduction to Near-Infrared (NIR) Analysis 

In the near IR regions, absorption due to molecular vibration 

appears. Therefore, substances can be identified by comparing 

spectral patterns, and quantitatively determined from the peak 

intensity. 

Absorbance is lower in the near IR region than in the mid IR region, 

so samples can be measured without dilution. The IRPrestige-21, 

which employs the Fourier transform method and offers spectra with 

Near-Infrared Applications 

Near-Infrared is used for qualitative and quantitative analysis, just as 

with the mid-infrared. Its applications include quality inspections of 

raw materials received, and endpoint quantitations for reaction 

processes. 

Applications and Accessories 

Multicomponent Quantitation of Liquid Samples 

The quantities of various components in liquid pharmaceuticals and 

foods are measured and controlled. For example, quantitation can be 

made of the quantities of components such as sugar and proteins 

when manufacturing soft drinks. In this case, the location and shape 

Acceptance Inspections for Raw Materials (Qualitative) 

When determining whether the correct raw materials have been 

delivered based on the spectral shape, select accessories in 

accordance with the form of the raw materials. After measurement, 

pass/fail determinations and library searches can be conducted using 

the PharmaReport program (Macro Platform required). 

If the sample is a powder, use either diffuse reflection equipment 

UpIR A, near-infrared integrating sphere IntegratIR A, or a reflectiontype 

fiber probe. 

For liquid samples, pastes, pellets, and cloths, use near-infrared 

integrating sphere IntegratIR A. 

For tablet samples (pharmaceuticals), use either near-infrared 

integrating sphere IntegratIR A or a reflection-type fiber probe. 

Difference Between UpIR A and IntegratIR A 

Diffuse reflection equipment UpIR A and near-infrared integrating 

sphere IntegratIR A differ as shown below. The selection should be 

made on the basis of the experimental objective. 

Benefits of IntegratIR A 

1. The peak strength is several times stronger than for UpIR A, and 

the obtained spectrum has a superior S/N ratio. 

2. Good data is obtained when measuring powdered samples in 

plastic bags. 

3. Measurements can be conducted of pellets, pastes, tablets, liquids 

and cloth samples. 

When the accessory is fitted to the sample compartment, the 

accessory type and its serial number are recognized automatically 

and the optimal measurement parameters are set. 

high wavelength precision, is optimal for identifying substances by 

comparing spectral patterns. Samples contained in glass or thin 

plastic containers can be measured directly. It is also possible to 

analyze a sample using a probe. Thus, sample pretreatment is easy, 

and the near IR measurement is also suitable for measuring samples 

that cannot be easily unpacked. 

of each component peak will depend on temperature. Therefore, 

measurement is conducted at a constant temperature using a heating 

transmission cell system. Here, the IRSolution PLS Quantitation 

Program will be required to create the calibration curves. 

For diffuse reflection equipment UpIR A and near-infrared integrating 

sphere IntegratIR A, the sample is prepared, and the prepared 

sample is then placed in the measurement window for measurement. 

Measurement can be conducted as is with the sample placed in the 

test tube included, or left in a plastic bag. In the latter case, however, 

there may be a significant impact from the bag's interference fringe. 

If the reflection-type fiber probe is used, measurement is possible 

without sampling. The probe can be inserted directly into the sample, 

or measurement can be taken directly of a sample placed in a glass 

bottle or plastic bag. In the latter case, however, there may be a 

significant impact from the bag's interference fringe. 

Benefits of UpIR A 

1. Cost 

2. Specialized for powdered sample analysis.
