Stir-Bar Sorptive Extraction of Trace Organic Compounds from Aqueous Matrices

As the push for green chemistry continues to grow, University of Almeria researchers created a review for ways chromatographic techniques could be more environmentally friendly.

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.

This new study presents a validated QuEChERS–LC-MS/MS method for detecting eight persistent, mobile, and toxic substances in escarole, tomatoes, and tomato leaves irrigated with contaminated water.

Haloacetic acid detection has become important when analyzing drinking and swimming pool water. University of Tasmania researchers have begun applying capillary liquid chromatography as a means of detecting these substances.
