A method for the determination of thiols by high-performance liquid chromatography (HPLC) with chemiluminescence detection has been developed. The method is based on the precolumn derivatization of thiols with o-phthalaldehyde and (Keywords: Chemiluminescence detection, high-performance liquid chromatography, o-phthalaldehyde, N-(4-aminobutyl)-N-ethylisoluminol, glutathione, cysteine, human blood)
