Isocyanates (NCO) are potent sensitizers and the largest cause of occupational asthma in the UK. Probably, MDHS 25/3 is the method most commonly used worldwide for the determination of organic NCO in air. This method uses an electrochemical (EC) detector to quantify oligo-NCO using derivatized NCO monomers as calibrants. This paper gives the results of a validation exercise using this method to quantify industrially used monomeric and oligo-NCO formulations. An expanded uncertainty of… CONTINUE READING
