Methoxyaniline. Determining in workplace air with HPLC
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2014, Vol 30, Issue 1
Abstract
A new procedure has been developed for the assay of methoxyaniline (anisidine) isomers with high-performance liquid chromatography with a FLD or UV-VIS detector. The method is based on the adsorption of 2-methoxyaniline (2-MA) and 4-methoxyaniline (4-MA) on Amberlite XAD-2. Adsorbed compounds are eluted with aceto-nitrile and derivatized with 9-fluo-renylmethyl chloroformate (FMOC CL). The resulted solutions are analysed with high performance chromatography with ultraviolet or spectro-fluorimetric detection. The working range of the analytical method is 0.025 ÷ 1 mg/m[sup]3[/sup] for a 200-L air sample. Limit of quantification: 0.01 µg/ml (FLD. The developed method of determining methoxyaniline (anisidine) isomers has been recorded as an analytical procedure (see Appendix).<br/><br/>
