Title A detector tube for the analysis of methyl isocyanate in air or nitrogen purge gas.
Bibliographic information Aug. 1974, Vol.35, No.8, p.468-475. Illus. 7 ref.
Abstract The need for a simple method to determine the level of methyl isocyanate (MeNCO) in vessels prior to entry or to locate leaks from process equipment led to the development of a detector tube. The useful range of the detector tube, the acceleration of the indicator reaction by increased temperature, the preparation of the detector tube and its calibration are described. The detector tube is based on the orange-to-yellow colour change obtained when MeNCO reacts with p-aminoazobenzene on silica gel. It is capable of detecting 1 to 30ppm MeNCO.
