Discover how to accurately analyze purity and impurities, determine sequences, and more with next-generation technologies from Agilent.

This application note describes a method for the rapid and simultaneous quantitation of benzene, 1,4-dioxane, and formaldehyde in personal care products (PCPs). Nine retail hair and skincare products from the United Kingdom were analyzed, with limits of quantitation (LOQs) for benzene in the low-ng g−1 range and 1,4-dioxane and formaldehyde in the sub- and low- μg g−1 range, respectively. Preliminary results indicate that SIFT-MS holds an 8- to 30-fold throughput advantage when compared to conventional gas chromatography (GC-MS).

Inside the Laboratory is a joint series with LCGC and Spectroscopy, profiling analytical scientists and their research groups at universities all over the world. This series spotlights the current chromatographic and spectroscopic research their groups are conducting, and the importance of their research in analytical chemistry and specific industries. In this “Inside the Laboratory –– Women in Separation Science” special edition PDF, we profile four industry leaders and the impact that their research is having in specific fields such as environmental analysis, forensics, national security, and drug development.

Biozen dSEC-7 accurately resolves AAV serotypes 5, 8 and 9 monomer from aggregates in under 10 minutes with consistent results across different mobile phase conditions.

Photodegradation of plastic products is known to accelerate weathering and the resulting release of chemical additives and particles to the environment, however these processes are complex. Here, eight different plastic consumer products were leached in double-distilled water under exposure to strong ultraviolet (UV) light for ten days, and the chemical composition of the leachates was compared to their respective dark controls. The leachates and plastic particles were investigated with a wide battery of chemical-analytical tools to broadly characterize the underlying processes and possible hazards. These covered (a) metal(loid) analysis, (b) microplastic analysis, (c) analysis of >70 organic target analytes and (d) nontargeted screening of the extracts.
