Abstract
A new procedure has been developed for the assay of 2,2'-dichloro-4,4'-methylenedianiline (MOCA) using high-performance liquid chromatography with diode array detector. MOCA was sampled from workplace air and derivative before determination using 3,5-dinitrobenzoyl chloride. The determination was carried out in the reverse-phase system (mobile phase: acetonitrile: water) using an Ultra C(18) column. The measurement range was 2-40 µg/m(3) for a 100 dm(3) air sample. Limit of detection: 7.9 ng/m(3) and limit of quantification: 23.8 ng/m(3).
