Abstract: | Objective : To establish a capillary GC method for the detetxaination of chloroform in Cinepazide Maleate. Methods : Chloroform was determined on HP-1701 capillary column using temperature programming. ECD was used as detector with a temperature of 250 ℃ ,the inlet temperature was 200 ℃, and DMF was used as the solvent. Results: The linear range of chloroform was 2. 4 - 120 mg. L-1(r = 0. 999 9). The average recovery was 99.4% ( RSD = 1.2% ). The detection limit was 0. 36 pg. The residual level for chloroform in 3 batches of samples was up to the standard stipulated in China Pharmacopeia. Conclusion: The method is simple,accu- rate,sensitive and reproducible,it can be used for the determination of chloroform in Cinepazide Maleate. |
