Quantitative determination of volatile organic pollutants in water using headspace–trap GC–MS

contributed by Markes International Ltd | 09/17/2018

This study shows that headspace samples acquired on the new Centri automated multi-mode sampling and concentration system for gas chromatography–mass spectrometry (GC–MS) can be used to quantify a wide range of volatile organic pollutants in water. Analysis of an 83-component standard based on the list in US EPA Method 524.2 showed chromatographic performance within the requirements of the method, as indicated by the mean values for linearity (R² 0.9990), reproducibility (6.9% RSD) and analyte recovery (90%), and a mean detection limit of 0.11 ppb.
