Determination of BTEX (residual solvents)

The determination of BTEX compounds (benzene, toluene, ethylbenzene and xylenes) makes it possible to quantify these volatile aromatic solvents in various matrices such as soils, water, packaging, materials, or industrial products.

These compounds are monitored because of their toxicity and polluting potential, particularly in the environmental, agri-food (migration), cosmetics and polymer sectors.

Analysis is generally performed by gas chromatography (GC), often coupled with mass spectrometry (GC-MS) or flame ionization detection (GC-FID). Samples can be prepared by liquid-liquid extraction, purge and trap, or headspace, depending on the matrix. This method allows for sensitive detection that meets regulatory requirements.

At YesWeLab , we collaborate with a carefully selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques or methods.
If you have any particular requirements, please do not hesitate to specify them in your request: our scientific team will do everything possible to respond accurately and promptly.
Since 2020, numerous manufacturers, distributors, and engineering firms have entrusted us with the management of their analyses, sending us their samples through our digital platform.
