聚乙二醇400／吐温－80混合固定液气相色谱法分离测定苯、甲苯和二甲苯的含量

DETERMINATION OF BENZENE TOLUENE AND 2-TOLUENE BY GAS CHROMATOGRAPHY USING A STATIONARY PHASE OF PEG/TUWEN-80

研究聚乙二醇－４００和吐温－８０混合固定液用于气相色谱分离测定苯、甲苯和二甲苯，得到合适的色谱分离条件，测定含量精度为０．１％

The benzene toluene and 2-toluene were determined by gas chromatography,using a stationary phase of 6201 support coated with polyglycol-400 and tuwen- 80.The method is simple and the results obtained are satisfactory.The detection linit for benzene toluene and 2-toluene is 0.1 %.
