Research and quantification of   BTEX


Light aromatic molecules such as Benzene, Toluene, Ethyl Benzene, Xylene, etc. are present in many industrial processes, in particular those involving petro-sourced raw materials.

Their great toxicity for humans and the environment make them particularly monitored and controlled molecules.
The acronym BTEX ( Benzene-Toluene-Ethylbenzene-Xylene ) defines this family of aromatic molecules:
- Benzene [71-43-2]
             - Toluene [108-88-3]
             - Ethyl Benzene [100-41-4]
             - Xylene isomers: p-Xylene [106-42-3] / m-Xylene [108-38-3] / o-Xylene [95-47-6]

The very volatile aspect of BTEX allows their detection and quantification via the HS-GCMS module .
Optimization of sample preparation protocols and analysis methods have made it possible to reach detection (LOD) and quantification (LOQ) limits of the order of ppb (ng / ml).
Calibration lines are established by injecting standards at known concentrations and allow precise quantification of BTEX in unknown samples.
Quantifiation des BTEX

The POLYMEX laboratory is therefore able to detect and quantify trace BTEX in samples with varied and complex matrices (Gels, liquids, emulsions, etc.).

This know-how responds to issues related to common themes in the industrial environment:

  • Quality control and production monitoring on raw material and finished product,
  • Search for contamination in polluted soils and waters,
  • [...]
