Abstract: Objective To establish a headspace capillary gas chromatgraphy for determination the residual organic solvents in piroxicam. Methods The residual solvents in piroxicam which are methanol , ethanol, toluene and dimethybenzene were determined by headspace GC on HP-INNOWax column(30 m×0.32 mm×0.25 μm),with FID detector,high purity nitrogen as the carry gas. Results Four residual organic solvents consisting of methanol, ethanol, toluene and dimethybenzene in piroxicam were completely separated and the samples coincided with the requirements. Conclusion The method is sensitive and accurate. It is suitable to the determination of residual organic solvents in piroxicam.
