Studies on the Spectrophotometric Determination of Gentamicin Sulfate and its Preparations

분광광도법에 의한 제제중 Gentamicin Sulfate의 정량에 관한 연구

The ability of gentamicin to form a stable coloured complex with copper (II) in a sodium carbonate buffer solution, which had a maximum absorption at 694nm, was used for the spectrophotometric quantitative determination of gentamicin sulfate. The calibration curve obtained was linear over the range of 200~2,000mcg per ml of the sample and the analysis was very well agreed with the microbiological method.
