This Mcerts certified solution measures and analyzes VOCs and BTEX (Benzene, Toluene, Ethylbenzene and Xylene) dissolved in liquid matrices. ...
Chromatotec Solutions Chromatotec has developed a solution equipped with an MCERTS certified GC FID, analyzing VOCs dissolved in liquids, by purge & trap sampling system (according to the EPA 502-2 standard) or headspace. This system therefore makes it possible to extract VOCs from a liquid and analyze them by a GC, in order to identify and quantify all the ...
To solve these problems, Chromatotec manufactures three gas generators to be connected to auto-GC : Hydroxychrom (H2) : high purity hydrogen generator is an important tool for the incoming H2 of several detectors like FID and FPD, utilized on BTEX, VOCs and other analyzers airmoPURE : zero VOC air production for analyzers using FID or FPD ...
Benzene is a hydrocarbon that appears as a volatile liquid, capable of evaporating rapidly at room temperature; it is colourless and easily flammable and is the progenitor of a family of organic compounds defined as aromatic, due to the characteristic odour. Benzene is a natural component of oil (1-5% by volume) and its refining derivatives. PROBLEM: BTEX analysis gives a great indication of ...
This technique allows for identifying and quantifying continuously hydrocarbons from ethane to naphthalene, including benzene, toluene, ethylbenzene, m&p-xylene and o-xylene (BTEX). The main goal of this work was to implement a new and simple method for sampling and determination of BTEX and PAHs in gas and solid phase in ambient air by using thermal ...

Environnement S.A leveraged its technical leadership in this field with an extensive experience, being one of the first companies creating its first BTEX analyser almost 20 years ago. The VOC72M third generation of the series is, up to now, the most compact and fully automated analyser on the market, self-contained and newly designed for providing equal performance to the ...

Reproducibility was lower from duplicate OVMs for BTEX (benzene, toluene, ethylbenzene, and xylene isomers) VOCs (7% RSD for 2-day samples) with better precision for longer sampling periods. Comparison of Ogawa NO2 samplers with chemiluminescence measurements averaged over the same time period suggested potential calibration problems with the chemiluminescence ...
