A procedure for the high-performance liquid chromatographic determination of tobramycin in serum is described using pre-column derivatisation with 1-fluoro-2,4-dinitrobenzene and subsequent chromatographic analysis on a reversed-phase column with ultraviolet detection. Gentamicin is used as the internal standard. The sensitivity is 0.5 mg/l with 50-microliters samples. Precision, expressed as the coefficient of variation, is 3% or better in the concentration range 0.5-16 mg/l. The absolute recovery of tobramycin is 41%. The analyses of serum samples obtained in an in vivo experiment correlated well with the results from a microbiological assay. The influence of variation of derivatisation conditions and the implications for the reliability of the internal standardisation were studied. The 2,4-dinitrophenyl tobramycin derivative was synthesized and its structure was proved to be the fully derivatized tobramycin. Side-products of the derivatisation reaction were isolated.
