2 Analysis of Volatile Organic Compounds (VOC) in Drinking Water or Surface Water Using external standard method, range of linearity is 0.5 - 100 μg/L. Correlation coefficient of each component is between 0.993 ~ 0.9992. The lowest detection limit is 0.001 mg/L for vinyl chloride.
U.S. Environmental Protection Agency (EPA) Method 8260B1 is an environmental method for analy-sis, identification and quantifica-tion of volatile organic compounds (VOCs) that have boiling points below 200 °C. The method speci-fies gas chromatography/mass spectrometry (GC/MS) analysis and is widely used in the U.S. and internationally for a
The analysis of volatile organic compounds (VOCs) in environmental water samples is usually performed by either headspace (HS) or purge and trap (P&T), with separation by gas chromatography (GC) and detection by mass spectrometry (MS). The P&T technique uses a continuous fl ow of carrier gas to purge any volatiles from the matrix onto an
