Some Suggestions on the Examination of Benzene in the Air by Gas Chromatography of Carbon Disulfide Extraction

Based on the experience of in-door air examination, and from the aspect of sampling pipe handling, carbon disulfide purification, sampling analysis and data revision, this paper puts forward some suggestions on the examination of benzene in the air by gas chromatography of carbon disulfide extraction, which is described in the appendix B of Code for Indoor Environmental Pollution Control of Civil Building Engineering (GB 50325-2001).
