2014/1/5 · An analytical strategy for comprehensive screening of target and non-target volatile organic compounds (VOCs) in surface water was developed, and it was applied to the analysis of VOCs in water samples from Daliao River. The target VOCs were quantified using purge and trap-gas chromatography-mass spectrometry (P&T-GC/MS). Among 20 water samples, 34 VOCs were detected at least once. For

2002/6/14 · Several different chemical types of volatile organic compounds (VOCs) have been detected in environmental waters. Alkylbenzenes, alkylnaphthalenes and chlorobenzenes were encountered in surface waters at levels up to 8 μg/l in highly polluted rivers close to Barcelona, where a high level of industrial activity is present [7] .

Organic compounds are oxidized and converted into CO 2, which is then quantified by the SSNDIR detector. The result is reported as the TOC content in both mass and concentration of carbon. The 1080 TOC Analyzer also supports other analytical approaches — including TC, TOC by subtraction (TC-TIC), and simultaneous determination of total bound nitrogen (TNb) using the optional TNb analysis module.
2016/4/1 · Samples were collected without any headspace in 4-L amber glass volatile organic analysis (VOA) vials, which were previously washed with distilled-deionized water and oven dried. Additional sampling, including replicates, to support an ongoing inorganic
