건립료기상색보법측정조분중이류화탄급새분함량적분석방법。장조분이갑순위용제희석，채용GC-9A 도진기상색보분리，FPD 검측기검측，지수법분별대조분중적이류화탄、새분진행정성정량분석。해방법분리효과호，측정적결과구유량호적준학도화정밀도，정개시양분석시간불초과6 min。
A chromatography method for determination of carbon disulfide and thiofuran content in the crude benzene was established. The method used methanol as the solvent, and crude benzene was separated by GC-9A gas chromatography, and was determined by FPD detector and qualitative and quantitative analysis of the carbon disulfide and thiofuran was carried out by the index method. The results show that, the method has good separating effect, accuracy and precision, the whole analysis process only needs less than 6 min.
