Title Cyclohexyl isocyanate - determination method
Original title Izocyjanian cykloheksylu - metoda oznaczania [in Polish]
Bibliographic information 2005, Vol.43, No.1, p.5-11.
Abstract A method for the determination of cyclohexyl isocyanate in air is described. Air samples are collected by drawing a known volume of air through glass fibre filters impregnated with a solution of l-(2-pyridyl)piperazine. The filters are transferred into 4 ml vials and extracted in a shaker with 2 ml of acetonitrile:dimethylsulfoxide (9:1) mixture. The obtained extracts are analysed by high performance liquid chromatography with ultraviolet or spectrofluorimetric detection. The working range of the analytical method is from 0.1 to 8.0 Ág/ml (0.0013 ¸ 0.106 mg/m3 for a 150 l air sample).
