| Abstract: | The content of residual organic solvents in Hydrochloride Nifekalant, such as methanol, chloroform, pyridine, tetrahydrofuran, N,N-dimethylformamide were determined by wide-bore quartz capillary column GC and external standard quantitative method. The correlation coefficient of the method is more than 0.99,relative standard deviation is less than 7.0%,and the detectability are as fellows, methanol:1×10-3μg,chloroform: 2×10-3μg, pyridine: 5×10-3μg,tetrahydrofuran: 2×10-3μg, N,N-dimethylformamide: 8×10-3μg. |
