Context & Challenges Following the publication of a ministerial decree on August 24, 2017, French industrial activities must meet compliance requirements on the quality of discharges of hazardous substances into water from environmental protection installation. Industrials are particularly targeted by these new guidelines and must adapt their monitoring systems. Chromatotec Solutions ...
Benzene is a natural component of oil (1-5% by volume) and its refining derivatives. PROBLEM: BTEX analysis gives a great indication of VOC emissions from an extended range of sources. The primary man‐made sources of BTEX are via emissions from motor vehicles and aircraft exhaust, losses during petrol manufacturing, spills and ...
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 laboratory ...

The analytical methods test for “BTEX”, which is an acronym for benzene, toluene, ethyl benzene, and xylene. ...
The benzene-toluene-ethyl benzene-xylene (BTEX) source analysis shows that BTEX at all heights were mostly associated with vehicle transportation activities on the ...
Ambient Volatile Organic Compounds (VOCs) were examined in a heavy traffic urban area in Bangkok, Thailand, on focusing monoaromatic compounds of benzene, toluene, ethylbenzene, m-, p- and o-xylene (BTEX). Passive samplers were used to measure ambient BTEX concentrations in the environment close to very congested roads. ...
Samples were collected from sandy and rocky sites for gas chromatography in five carbon ranges of gasoline, diesel oil, engine oil, BTEX, and PAH. The GC analysis revealed the highest pollutant concentration levels in autumn and the lowest in summer; moreover in rocky beaches analysis indicated that a major portion of the oil pollution in the ...
Because of the widespread use and history of indiscriminate disposal practices of gasoline and fuel oils, their analysis in environmental samples is in high demand. Gasoline and diesel are both complex mixtures containing up to 400 individual compounds. The BTEX group (Benzene, Toluene, Ethylbenzene, and the Xylenes) are naturally occurring constituents of ...
A number of different stationary phases have been used for analyzing benzene, toluene, ethylbenzene, and xylene hydrocarbons (the BTEX) compounds). Capillary columns based on a nonpolar shape-selective phase, a chiral stationary phase, and a polyalkylene glycol phase, and support coated open tubular columns (SCOT), exhibit differing abilities to resolve these compounds. A Bentone ...
