Sample Preparation ASTM D5815 (or D1996) method recommends using a reflux apparatus for extracting additives in polymer. This requires periodic operator intervention over the 1.5-hour-long extraction period. To find a time-saving sample-preparation method, ultrasonic extraction was also tested, producing comparable results in 30 minutes. In terms of extraction efficiency, there is not much difference between these two methods. Figure 9 shows very good overlays of extractions by reflux and ultrasonic extraction methods for a LLDPE. Conditions are identical to those in Figure 1. Conclusions Liquid chromatography with ultraviolet/visible detection is an effective tool for analyzing additives in polymer formulations. The Agilent 1200 Series RRLC system equipped with RRHT 1.8-µm columns was used to achieve up to 10 times faster than the conventional HPLC method. The ultrasonic extraction method allowed fast extraction without user intervention for a significant reduction in overall analysis time. Total time saved was more than 80 minutes per sample when compared Normal 250 200 150 100 50 1 Tinuvin P 7 Irganox 1076 1 www.agilent.com/chem to the conventional analysis and extraction methods.

Waldbronn, Germany Ruediger Helling Landesuntersuchungsanstalt für das Gesundheits- und Veterinärwesen, Saxony, Dresden, Germany Developing a UHPLC method for UV-based detection and quantifi cation of primary aromatic amines in low concentrations Application Note Consumer Products mAU 60 50 40 30 20 10 0 _ 10 Abstract 2 4 6 8 10 12 14 16 min This Application Note demonstrates that stringent sensitivity requirements for the detection of potentially harmful primary aromatic amines can be fulfi lled when using an Agilent 1290 Infi nity LC System equipped with the 1290 large volume injection kit. This enables the Agilent 1290 Infi nity Autosampler for injection volumes up to 120 µL for sample enrichment on the column. A high sensitivity 60-mm Max-Light fl ow cell in the Agilent 1290 Infi nity Diode Array Detector gives additional detection sensitivity.
