Ambient air. Standard method for the measurement of benzene concentrations - Automated pumped sampling with in situ gas chromatography Ingestion-build-242630 The extensive use of electro-technical1 Scope This European Standard specifies a semi continuous measurement method for the determination of the concentration of benzene present in ambient air based on automated sampling and analysis by gas chromatography. This European Standard describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate automated gas chromatograph (GC) by means of type approval tests. It also includes the evaluation
