Determination of Waste BTEX (Benzene, Toluene, Ethyl Benzene, Xylene) (EPA 5021 A Method)

Determination of Waste BTEX (Benzene, Toluene, Ethyl Benzene, Xylene) (EPA 5021 A Method)

The EPA 5021 A method, developed by the United States Environmental Protection Agency (EPA), describes a test method for the determination of volatile organic compounds in various sample matrices using equilibrium cap analysis. The full name of the method is: SW-846 test method 5021A: Volatile organic compounds (VOCs) in various sample matrices using equilibrium cap analysis.

Determination of Waste BTEX (Benzene, Toluene, Ethyl Benzene, Xylene) (EPA 5021 A Method)

This method describes the preparation of volatile organic compounds in soil/sediment, solid waste, aqueous and water-miscible liquid samples by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). This method is applicable to a wide variety of organic compounds with sufficiently high volatility to be effectively removed from samples using the conditions described.

This method directlyIt is designed for use in samples containing low levels of volatile organic compounds or their aqueous dilutions to be analyzed by vapor partitioning. It also includes a solvent extraction procedure for solid samples or oily materials containing high concentrations of volatile organic compounds.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests performed in this context, there are also waste BTEX (benzene, toluene, ethyl benzene, xylene) determination (EPA 5021 A method) services.
