Volatile organic compounds (VOCs) in soils - Springer

2017-8-25 · Abstract Soils may act as sources or sinks of volatile organic compounds (VOCs). Many of the formed VOCs are produced by microorganisms, and it would be a challenge to investigate soil microbial communities by studying their VOC profile. Such “volatilomics” would have the advan-tage of avoiding extraction steps that are often a limit in

VOC detector MX6 volatile organic compounds - …

2019-4-23 · The MX6-VOC gas detector needs to be calibrated twice a year in order to ensure proper operation. The photoionization sensor (sensor technology for VOC detection) can detect volatile organic compounds with a ionization potential below 10.6 eV. The MX6-VOC measuring range is set between 0 and 2,000 ppm in 0.1 ppm increment.

California Air Resources Board (CARB) issued regulations on limitation of VOC content in consumer products, namely antiperspirants and deodorants, aerosol coating products, hairsprays, cleaners, air fresheners, adhesives, and many more.The intention is to reduce the amount of smog-forming volatile organic compounds (VOC), toxic air contaminants, and greenhouse gases that are emitted from the

TOC - Total Organic Carbon - LAR Process Analysers

The Total Organic Carbon (TOC) is one of the most important composite parameters in the assessment of the organic pollution of water. Since it includes all carbon compounds as one mass, it is exactly defined and an absolute quantity. Therefore, it may be determined directly.
