Applications of purge-and-trap gas chromatography - Mass spectrometry for the determination of volatile organic compounds in water

Abstract

Volatile organic compounds (VOCs) enter water systems through rainfall, through intentional or unintentional industrial or domestic releases as well as through leaching of (from) contaminated sources. The adverse effects of VOCs on health, the environment, and scientific experiments has led to monitoring of VOCs in various aqueous media.Purge-and-trap gas chromatography-mass spectrometry (PAT GC-MS) was applied to three applications of monitoring VOCs in water; (i) to the yearlong monitoring of VOCs present in rainwater collected in the western region of Singapore, (ii) in the qualification and quantification of leachable VOCs from syringe filters, and (iii) in the assessment of
