Abstract
Objective:A headspace capillary GC method was established for the determination of the residual solvents in Xueshuantong injection .Method:The Chromatographic conditions adopted were DB -624 capillary column(30m ×0.25mm ×1.40μm),with nitrogen as carrier gas and FID as detector .The temperature pro-gram and split injection mode were used .Results:The calibration curves of Methanol , ethanol, acetone,n-hexane, ethyl acetate, n-butyl alcohol, benzene, toluene, xylene,1,2-2 ethyl benzene and diethyl benzene were had a good linear relationship .The precision of RSD was all below 2.8%.The average recovery rates were 99.5%~104.1%(RSD=1.0%~4.0%).Conclusion:The method is accurate and reliable.It can be used for detection of the residual solvents in Xueshuantong injection .关键词
