| Abstract: | By using Sulfuric acid as absorbing liquid, pyridine in air was determined by headspace sampler-gas chromatography with capillary column and FID. The liner ranges were 0-98.3 mg/L, r>0.9995. When sampling 30L, the minimum detection concentrations were 0.006 mg/m3, and relative standard deviation was lower than 3.1%, and the recoveries was 95.3% to 99.6%. |
