盐酸格拉司琼中有机溶剂残留量的毛细管GC测定

Determine organic residual Solvents in Granisetron Hydrochloride by GC

目的建立了毛细管气相色谱法测定盐酸格拉司琼中氯仿、二氯甲烷、甲苯的有机溶剂残留量。方法用HP-FFAP毛细管柱,程序升温法。结果各溶剂的线性关系良好(r>0.997),精密度较好。

Objective To establish a determination method of the residual chloroform, diehloromethane and methylbenzene in Granisetron Hydroehloride by GC. Methods HP - FFAP capillary column and programmed temperature were used. Results The method had a good precision and the linear Correlation of residue solvents was good.
