PFAS Lists and Libraries

To better detect polycyclic aromatic hydrocarbons in the human body, a UHPLC–MS/MS method was developed and tested on urine samples from workers exposed to diesel exhaust.

Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.

In this article, you’ll find some of the top content that was published on LCGC this week, including a technical article on food flavor and an interview with the president of Shimadzu Europa.

In a new study, researchers explored a new approach for detecting pesticide residues in water samples, based around ionic liquid-based dispersive liquid–liquid microextraction (IL-DLLME).

A new analysis method for detecting bisphenols in environmental sources was tested using loofah sponges and solid-phase extraction.

In a new study, researchers used GC–MS and LC–MS were used to detect composition fraud in food supplement creation.
