NMR Method of Assay for Gentamicin

Abstract

Nuclear Magnetic Resonance (NMR) has been used successfully to assay Gentamicin dosage forms. The method gives 100.5% accuracy with a variation of 2.3% for pure samples. It is a fast method of analysis. An assay which normally takes 14 or 18 hours by microbiological or ion exchange chromatographic methods respectively can now be performed in 30 minutes by the use of NMR.
