A sensitive and very rapid assay for acetaminophen was developed based on the combination of high‐performance chromatographic columns with a thin‐layer electrochemical detector. Application to liquid and solid dosage forms and body fluids has been demonstrated. Great advantage derives from the detector selectivity, which permits discrimination against many potentially interfering substances without need for extensive separations or formation of derivatives. As little as 0.005% of the hydrolysis product, p‐aminophenol, can be detected in the presence of the intact drug following cation‐exchange chromatography. Acetaminophen can be quantitatively determined in serum on the 50‐ng/ml level by liquid chromatography using a pellicular polyamide packing. |
