Determination of organonitrogen compounds in air using liquid chromatography and mass spectrometry - Amines and aminoisocyanates using dibutylamine and ethyl chloroformate derivatives Ingestion-build-134498 for the primary containment and1 Scope This part of ISO 17734 gives general guidance for the sampling and analysis of airborne amines and aminoisocyanates in workplace air. It is strongly recommended that the determination of amines and aminoisocyanates is made together with the determination of isocyanates in air, using DBA as a reagent (see ISO 17734 1). The method can be used for simultaneous determinations of amines, such as 4,4' methylenediphenyldiamine (4,4' MDA), 2,4 and 2,6
