Objective: To establish a method for the determination of residual solvents in Rg1 by GC. Method: The detector was FID.The analytical column was DB-624(0.32 mm×30 m
0.25 μm).The injector temperature was 200℃
and the detector temperature was 200℃.The column temperature was 50℃.Nitrogen as the carrier gas and the water as solvent media. Result: It had a good linearity in the experimental concentration.The detection limit of ethanol was 1.0 ng·mL-1.The RSD of precision was all less than 1.0%.The average recovery was 90%-105%. Conclusion: This method was simple
sensitive. accurate and can be used for the detection of f residual solvents in Rg1.
