Volatile Organic Compounds (VOCs) are organic chemicals for the most part dangerous for human health or harmful for the environment. Some of them are mutagens, teratogens or carcinogens. This is why VOCs are highly regulated by norms. The qualitative confirmation, quantitative accuracy and precision required in current regulations demand for high performing analytical solutions.
EPA Method 8015D - NONHALOGENATED ORGANICS USING GC/FID This method may be used to determine the concentrations of various nonhalogenated volatile organic compounds and semivolatile organic compounds by gas chromatography. This method is applicable to the analysis of other analytes, including triethylamine and petroleum hydrocarbons. The petroleum hydrocarbons include gasoline range organics (GRO) and diesel range organics (DRO). Groundwater or surface water samples generally must be analyzed in conjunction with EPA Methods 5021, 5030, 5031, 5032, 3510, 3520, or other appropriate preparatory methods to obtain the necessary quantitation limits. EPA Method 3535 (solid-phase extraction) may also be applicable to some of the target analytes.
EPA Method 5021A - VOLATILE ORGANIC COMPOUNDS IN VARIOUS SAMPLE MATRICES This method is a general purpose method for the preparation of volatile organic compounds (VOCs) in soil/sediment, solid waste, aqueous and water-miscible liquid samples for determination by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). The method is applicable to a wide range of organic compounds that have sufficiently high volatility to be effectively removed from samples using an equilibrium headspace procedure.
