Test results using the NIOSH analytical method S252 for methyl- isocyanate (624839) are reported. Samples were collected on XAD-2 resin coated with 1-naphthylene-methylamine and were analyzed by high pressure liquid chromatography (HPLC) with a fluorescence detector, or were collected on resin coated with N-4-nitrobenzyl-N-n- propylamine (62869743) and analyzed by HPLC with an ultraviolet absorbance detector. Fluorescence reactions are described, and calibration data is included. Neither method was satisfactory due to slow reaction times and instability of the derivatizing agents.
