Analysis of volatile organic compounds (VOCs) in water by HS-GC-MS Method
Introduction
Several kinds of volatile organic compounds (VOCs), such as disinfectant byproducts and/or ground water contaminants are monitored by regulation in each country. Especially, VOCs contamination level in tap water are always monitored by governments, municipalities or water utilities. It is well known that the headspace(HS)-Gas Chromatograph(GC)-Mass Spectrometer(MS) is useful for the analysis of such VOCs, HS-GC-MS is employed as the standard analysis method for VOCs in water by the U.S. Environmental Protection Agency (US EPA) and by the Japanese Ministry of Health, Labour and Welfare. Since the rapid analysis method for 25 kinds of VOCs within 20 minutes could be achieved by using JMS-Q1600GC UltraQuad™ SQ-Zeta gas chromatograph-mass spectrometer combined with HT2850T GC autosampler from HTA, the detailed measurement condition and measurement results are reported in this study.
