Abstract
Headspace sampling combined with capillary column gas chromatography–mass spectrometry analysis was evaluated for use in the investigation of priority pollutants in water and wastewater. A 3 mL sample loop and cryogenic trapping at ‐80°C were employed to increase the sensitivity into the nanogram‐per‐litre range, and excellent reproducibility was found in the low microgram‐per‐litre range. Separations were accomplished with a coated 30‐m × 0. 32‐mm fused silica capillary column. Mass spectral data were acquired by selective ion monitoring from 50 to 500 amu. The method was applied to water and wastewater samples with good results.Keywords
