QUANTITATION OF GENTAMICIN SULFATE IN INJECTABLE SOLUTIONS BY CAPILLARY ELECTROPHORESIS

The results presented in this communication establish the use of capil lary electrophoresis as a tool in the analysis of injectable solutions containing the antibiotic complex gentamicin sulfate. The utilization of a berate buffer leads to the separation of the individual componen ts and their visualization by direct UV detection. This rapid and stra ightforward procedure yields qualitative and quantitative information simultaneously, and could be utilized as an alternative to the multipl e assays required by current US Pharmacopeia protocols.
