Title: Determination of Benzene Hydrocarbon by Capillary Column Gas Chromatography
Abstract: Gas chromatography method had high sensitivity and good linearity.The separation of benzene,xylene,styrene and n-hexane were studied with using ZB-50 capillary column to establish a capillary gas chromatographic method for the determination of benzene mixture.The results showed that using temperature programming was better than using constant temperature in the separation of several substances,which could obtain satisfactory peak shape.Using split injection was better than the splitless one.The method of gas chromatography had a good repeatability and a high precision.The relative standard deviation was 3.45%~4.23% and the recovery of standard addition was 95.2%~97%.
