Analysis The specimen is placed in the sample compartment and the spectrum is recorded; a typical spectrum is shown in Figure 6. The presence of an absorption band at 695 cm -1 suggests that the resin contains a sorbitolbased clarifier that can interfere with the statistical ethylene measurement at 733 cm -1 . If the presence of this clarifier is confirmed, the statistical ethylene measurement must be corrected to compensate for the absorbance of the clarifier. Certain anti-acid additives can also have an effect on the measurement but are usually ignored since these compounds are present at very low concentrations. Figure 6. Typical absorption bands for statistical and block ethylene With the ratio defined from the Method Configuration section, the new method is ready to be used to obtain at least triplicate measurements of each calibration standard. Unknown polymer coupons should also be run with a minimum of three measurements around the coupon. This process is made simple and convenient with the DialPath or TumblIR transmission cells. Users can see the exact point of measurement in real time, and quickly reposition the sample for the replicate measurements. Plot the values measured for the ratio relative to the statistical ethylene concentration (Figure 2), and insert the slope and offset values back into the method as shown in Figure 5. Once the slope and offset values have been entered, the MicroLab PC FTIR software method will report the statistical ethylene concentration. The MicroLab PC method, Polymer – Statistical Ethylene in Polypropylene v1, includes the calibration data from Figure 2. This calibrated method is available with the Agilent 5500 and 4500 Series DialPath or TumblIR FTIR spectrometers, as well as the Cary 630 FTIR spectrometers. This method and software performs all the calculations automatically and reports the final value as % statistical ethylene (Figure 7). The values obtained from triplicate determinations should be averaged to give the final reported concentration. Conclusion Figure 7. The MicroLab PC software prediction result for a 2.6% statistical ethylene in polypropylene sample This analytical method demonstrates how the Agilent Cary 630 FTIR can be used to easily and accurately measure polymer thin films. The unique sampling capabilities of the DialPath and TumblIR provide a simple mechanism to mount your sample, while the step-by-step method-driven software with color-coded, actionable results guides you through your analysis to ensure that your samples are measured with minimum effort and highest accuracy. 5
Authors Dr. Wayne Collins*, John Seelenbinder † and Frank Higgins † Agilent Technologies * Wilmington, DE, USA † Danbury, CT, USA Determination of Irganox 1010 in polyethylene by infrared spectroscopy Analytical method Polymers Scope This method is for the determination of Irganox 1010 and chemically identical antioxidants in polyethylene where the additive package is known. The method utilizes a characteristic ester carbonyl band associated with the additive that is common in many other additives. Therefore, the total additive package must be known to confirm that other additives present do not contain bands that would interfere with the measurement. The method is typically used for process control of additive addition and is not recommended for filled or pigmented resins. The sample must be pressed into a film or coupon prior to the analysis.
