• Liquid chromatography on an amide stationary phase with post-column derivatization and fluorimetric detection for the determinat

  The separation of streptomycin and its derivative dihydrostreptomycin using ion-pair liquid chromatography is proposed. The method is based on the use of a new stationary phase based on a ligand with amide groups and the endcapping of trimethylsilyl which avoids the appearance of tailed peaks.
