title: A simple, sensitive assay for the spermicide nonoxynol-9 in biological fluids by high-performance liquid chromatography.
abstract: A new high-performance liquid chromatographic technique has been developed to quantitate nonoxynol-9 in serum, urine, and vaginal fluid. The method is rapid, involves minimal sample preparation, and can be used to analyze a large number of biological fluid samples. The assay elutes a single nonoxynol-9 peak with no interfering components. This was accomplished using a 10-microns pelicular packed amine column, a normal-phase solvent system, and fluorescence detection. Nonoxynol-9 levels as low as 0.23 micrograms/mL in urine can be detected.
