| Abstract: | Objective To determine residual organic solvent volume in clindamycin phosphate by headspace gas chromatography. Methods The determination was performed on DB- 624（30 m × 0. 53 mm, 3 μm） capillary column with temperature programming, the detector temperature was 250 ℃, the carrier gas was nitrogen, the flow rate was 3 mL/min and the split ratio was 1 ： 1. Results The contents of five residual organic solvents in three batches of samples complied with the specification requirements. Conclusion The method is proved to be sensitive, accurate and reliable. It is suitable to be adopted in the analysis of testing the residual organic solvent in elindamycin phosphate. |
