A quantitative analysis of salicylamide in microplasma volumes by high-performance 1iquid chromatography using fluorescence detection is reported. The procedure is extremely simple and very rapid, involving the direct introduction of the plasma sample on the HPLC column. The assay procedure is linear over the concentration range studied, 0–100 ng/ml with correlation coefficient for the linear regression, r = 0.998. This assay procedure enables the detection of salicylamide as low as 5.0 ng/ml in plasma, using sample volume of 100 μl.
