This part of prEN 14662 gives general guidance for the sampling and analysis of benzene in air by pumped sampling, thermal desorption and capillary gas chromatography. This part of prEN 14662 is in accordance with the generic methodology selected as the basis of the European Union reference method for the determination of benzene in ambient air [1] for the purpose of comparison of measurement results with limit values wiht a one-year reference period. This part af prEN 14662 is valid for the measurement of benzene in a concentration range of approximately 0,5 mg/m 3 to 50 mg/m 3 in an air sample typically collected over a period of 24 hours. The upper limit of the useful range is set by the sorptive capacity of the sorbent and by the linear dynamic range of the gas chromatograph column and detector or by the sample splitting capacity of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of benzene and/or interfering artifacts on the sorbent. Artifacts are typically sub ng for sorbents such as Carbopack B, but higher levels of aromatic hydrocarbons have been noted in other sorbents.
