气相色谱法同时测定乙酸乙酯、乙酸丁酯、环己酮和苯系物

Determination of Ethyl Acetate,Isobutyl Acetate,Cyclohexanone and Benzene Series by Gas Chromatography

采用活性碳吸附,二硫化碳解吸进样,利用DB-1毛细管色谱柱采用恒温条件分离,以FID为检测器,同时测定空气或废气中乙酸乙酯、乙酸丁酯、环己酮、苯系物。结果表明,该方法分离效果好,精密度高,准确度高,分析时间短,适合空气或废气环境分析的要求,结果令人满意。

A method for the determination of ethyl acetate,isobutyl acetate,cyclohexanone and benzene series in air and exhaust gas was developed.Ethyl acetate,isobutyl acetate,cyclohexanone and benzene series in air and exhaust gas were separated and analyzed by the DB-1 capillary gas chromatography,using active carbon as adsorption solution,carbon disulfide as dissolvention,FID as detector.The method has good separability,precision and accuracy,and analytical time was short.The method was applicable for environmental determination of air or exhaust gas with satisfactory results.
