This European Standard specifies procedures for the sampling, preparation and analysis of samples of gaseous or vapour phase organic components such as those arising from solvent using processes and can be used as a reference method. NOTE: See Council Directive 13/99/EEC. The results obtained using this Standard are expressed as the mass concentration (mg/m3) of the individual gaseous organic components. This Standard is suitable for use in the range of about 0,5 mg/m3 to 2000 mg/m3. The method utilizes adsorption and is suitable when the desorption efficiency is greater than 80%.
