<strong>InfraCal</strong> <strong>TOG</strong>/<strong>TPH</strong> <strong>Analyzers</strong><strong>for</strong><strong>Oil</strong> <strong>and</strong> <strong>Grease</strong> Measurementswww.WilksIR.com
Portable Field or Lab AnalyzerResults in < 30 secondsRugged <strong>and</strong> Easy to UseOver 2000 in use worldwide today
Off shore oil rigsRefineriesIndustrial WastewaterMetal Parts Cleaning
Monitoring Using an Offsite Lab=Delayed Results
Monitoring Using an Offsite Lab Typical commercial laboratory turn around - twodays to two weeks In-house hexane/gravimetric—several hours Results in the discharge of effluent aboveregulatory limit <strong>for</strong> extended time Add costs in time <strong>and</strong> dollars
Non Compliance The sooner the industry or regulating agencycan detect non compliance The sooner the problem can be corrected
What is needed:A quick, accurate <strong>and</strong> simplefield <strong>and</strong>/or in-plant analysis:Available with the<strong>InfraCal</strong> <strong>TOG</strong>/<strong>TPH</strong> Analyzer
Two different models availabledepending on desired measurementrange <strong>and</strong> extraction solventModel CVHModel HATR-T2T2
CVHMinimum Detection Limit 2 ppm 8 ppmSolventPerchloroethylene, Freon,S-316HATR-T2hexane, pentane,Vertrel MCAComponent Measured Measures all hydrocarbons Measures hydrocarbonswith a boiling point higherInstrument Repeatability +/- 1 ppm +/- 2 ppmOtherSolvents are heavier thanwater <strong>and</strong> require a seperatoryfunnel or inverted vial with asepta cap to collect a solventsample.than the solvent—volatilehydrocarbons will beevaporated along with thesolvent.Solvents are lighter thanwater <strong>and</strong> solvent samplecan be collected from thetop of the container.
Measuring <strong>Oil</strong> in Water withthe <strong>InfraCal</strong> <strong>TOG</strong>/<strong>TPH</strong> Analyzer Acidify sample to pH of 2 Add 10 ml solvent to 100ml sample (10 to 1 ratio) Shake <strong>for</strong> 2 minutes A portion of the solvent ispresented to the analyzer <strong>for</strong>analysis
Basic Measurement ConceptInfrared Analysis:Hydrocarbons have a characteristicabsorbance in the infrared region:2930 cm- 1 or 3.4 microns
Spectrum of a hydrocarbon (red)Overlaid with a 3.4 micron filter (black)
Infrared AbsorbanceThe amount of energy absorbedis proportional to the amount ofoil/grease in the sample:A higher oil <strong>and</strong> grease concentrationhas a higher infrared absorbanceA lower oil <strong>and</strong> grease concentrationhas a lower infrared absorbance
The Measurement of <strong>Oil</strong> usingHexaneModel HATR-T2T2
The hexane evaporates leaving anoil film on the crystal<strong>Oil</strong> FilmSourceATR crystalA = log (I r / I a )Filters(I r / I a )DualDetector
Infrared light (source) is focused on theend of the crystal<strong>Oil</strong> FilmSourceATR CrystalA = log (I r / I a )Filters (I r / I a)DualDetector
The infrared light reflects offthe surface of the crystal<strong>Oil</strong> FilmSourceATR CrystalA = log (I r / I a )Filters (I r / I a )DualDetector
At each reflection, the infrared lightpenetrates into the oil film <strong>and</strong> is absorbedby the oil at 2930cm -1Infrared lightSample<strong>Oil</strong> Film

Preset timer allowshexane to evaporate After timercountdown <strong>and</strong> 15second run time Value is displayed
Cleaning the Trough Crystal Add enough solventto cover crystal Wipe slowly acrossthe crystal
Analysis ProcedureThe whole analysis, from samplecollection to final result, takes under 15minutesAn operator with minimal training c<strong>and</strong>o the analysis
Measurement Range Hexane extraction: 10- 300 ppm** the upper limit can be extended by dilution
Repeatability of the Hexane/InfraredMethodRepeated runs on same sample: + 01Independent applications of sample: + 02Independently prepared samples: +03** Repeatability is dependent on how carefully theanalyst does the extraction

ASTM Method D 7066-0404 Uses a transmission cell - Model CVH Measures volatile constituents
The Measurement of IR Absorption ofan <strong>Oil</strong> Sample with a CuvetteSampleFilters (I R / I A )SourceDetectorsA = log I R / I AInfraRed light passes through the cuvettefilled with solvent from the sample extract
The infrared light is focused on toa detector containing a2930cm - 1 filterSampleFilters (I R / I A )SourceDetectorsA = log I R / I AThe amount of IR energy absorbed by thesample correlates to the concentration ofoil <strong>and</strong> grease in the sample
Cuvette is filled withsolvent extract
Cuvette is placed in the analyzerAfter 30 seconds,<strong>Oil</strong> <strong>and</strong> <strong>Grease</strong> value is displayed
Measurement Range S-316 or Perchloroethylene: 2 -300ppm** the upper limit can be extended by dilution

Comparing Different AnalyticalProcedures
<strong>Oil</strong> <strong>and</strong> <strong>Grease</strong> Not a unique chemical entity A mixture of chemical species that varyfrom source to source It is defined by the analytical procedure,ie: infrared, gravimetric, GC/FID
Comparing Different Analytical Infrared GravimetricProcedures Gas Chromatograph/FlameIonization Detector (GC/FID) Ultra VioletEach method measures different physicalproperties
TechnologyInfraredGravimetryGC/FIDUltra VioletWhat isMeasuredAll analytes removed fromthe samples by theextraction solvent thatcontain a C-H stretchingabsorption.All analytes removed fromthe sample by the extractionsolvent that are notvolatilized.All analytes removed fromthe sample by the extractionsolvent that can bechromatographed <strong>and</strong> thatrespond to the detector.Aromatics onlyWhat is NotMeasuredVery polar organicsVolatilesVery polar or involatilecompounds dependingon choice of column,temperature program,time, etc.Aliphahtics
Note:Ultraviolet (UV) measures only the aromatichydrocarbons in a water sample. If thearomatic/ aliphatic ratio changes, thereading will not be correct.Infrared measure both the aromatic <strong>and</strong> thealiphatic hydrocarbons.
