The chemical analysis of organic compounds in environmental samples is often targeted on predetermined analytes. A major shortcoming of this approach is that it invariably excludes a vast number of compounds of unknown relevance. Nontargeted chemical fingerprinting analysis addresses this problem by including all compounds that generate a relevant signal from a specific analytical platform and so more information about the samples can be obtained. A DHS−TD−GC−MS method for the fingerprinting analysis of mobile VOCs in soil is described and tested in this article. The analysis parameters, sorbent tube, purge volume, trapping temperature, drying of sorbent tube, and oven temperature were optimized through qualitative and semiquantitative analysis. The DHS−TD–GC−MS fingerprints of soil samples from three sites with spruce, oak, or beech were investigated by pixel-based analysis, a nontargeted data analysis method.

Our annual review of new liquid chromatography columns and accessories, introduced at Pittcon and other events.

LCGC Europe

This instalment describes high performance liquid chromatography (HPLC) and related products introduced at Pittcon 2018 in Orlando, Florida, USA, and in the year prior. It highlights new HPLC and mass spectrometry (MS) systems, modules, chromatography data systems, and other HPLC-related software and provides brief descriptions of their significant benefits and innovative features.

Craig Wheelock discusses the obstacles facing chromatographers involved in metabolomics and the benefits of data independent acquisition-mass spectrometry (DIA-MS) in this field.
