Determination of residual solvents in gatifloxacin by headspace capillary gas chromatography

  • Received Date: 2009-08-16
  • Objective :To establish a method for determination of five residual solvents in gatifloxacin. Methods : The residual organic solvents which are ethanol,acetonitrile,dichloromethane,ethyl acetate,toluene were quantitatively determined by headspace GC on DM-624 column,90%DMF as solvent media,with FID detector,high purity nitrogen as the carrier gas. Results : Five residual solvents were completely separated.There was a good linearity(r=0.999 7~0.999 9).The detection limit of ethanol,acetonitrile,Dichloromethane,ethyl acetate,toluene were all less than 3μg/g;the RSD of precision was less than 5%;the average recovery rate of the preparation was in the range of 94.8%~98.6%. Conclusion :The method is simple,rapid,sensitive and can be used for the quality control of gatifloxacin.
