A Collaborative Approach to Dealing with Contaminants of Emerging Concern
Contaminants in surface water and drinking water supplies arising from pharmaceutical and personal care product use as well as other compound sources pose a difficult challenge for analytical chemists. Thomas Letzel from the Technical University of Munich in Germany, spoke to LCGC to discuss collaborative research taking place in Europe to address contaminants of emerging concern in water analysis.

Large-Volume Injection LC–MS-MS Methods for Aqueous Samples and Organic Extracts
Environmental sample analysis by large-volume injection (LVI) in combination with liquid chromatography–tandem mass spectrometry (LC–MS-MS) is described for polar and nonpolar analytes in both aqueous samples and organic extracts. LVI is the direct introduction of large sample volumes (for example, 900–1800 µL) into the LC system for separation and subsequent detection. The practical benefits of LVI include faster sample preparation times, lower detection limits, and minimal waste generation.
GC–MS and UHPLC–MS-MS Analysis of Organic Contaminants and Hormones in Whale Earwax Using Selective Pressurized Liquid Extraction
This work addresses two challenges: developing a technique capable of measuring ppb levels of hormones, and developing an SPLE technique capable of extracting contaminants and hormones from a single sample without additional cleanup steps.
