Innovative Approaches to PFAS Detection and Quantification

A new gas chromatography-based approach involving skin-contact sampling bands was used to detect potential malaria infections.

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 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.

A new dried spot-based technique involving untargeted liquid chromatography coupled with high-resolution mass spectrometry was testing for characterizing foodstuffs.
