  • Objective To develop a method of headspace capillary gas chromatography for determining residual organic solvents in loperamide hydrochloride. Methods The carrier gas was nitrogen and FID as detector. The nine organic solvents including methanol, isopropanol, n-hexane, ethyl acetate, tetrahydrofuran, chloroform, methyl isobutyl ketone, toluene, benzene were separated on a DB-624 capillary column(30 m×0.32 mm×0.25 μm)by programmable increased temperature and headspace gas chromatography. Results The nine organic solvents were separated and each of them showed linear relationship in the concentration range measured. The recoveries and RSDs were in range from 95.2% to 102.3% and 0.8% to 2.9%, respectively. Conclusion The method was simple, accurate and reproducible.
