| Abstract |
This revised guidance note (see CIS 88-955 for previous edition) describes a laboratory method for the determination of organic isocyanates in air. Principle: a measured volume of air is drawn through a glass impinger containing 1-(2-methoxyphenyl) piperazine absorbing solution; organic isocyanates react to form non-volatile urea derivatives; the resultant solution is concentrated and analyzed by high performance liquid chromatography with ultraviolet and electrochemical detection. Scope: the method is suitable for sampling over periods of 10min to 8h for both personal and fixed location monitoring. Analytical range: 7 to 140µg NCO/m3 for a 10L sample volume; for an 8h (30L) air sample the detection limit is 2µg NCO/m3. Aromatic amines will produce interference. Guidance is also given on properties, uses and toxicity of organic isocyanates and first aid following significant exposure. |
