Determination of organonitrogen compounds in air using liquid chromatography and mass spectrometry - Isocyanates using dibutylamine derivatives Ingestion-build-96603 these are covered by PAS1 Scope This part of ISO 17734 gives general guidance for the sampling and analysis of airborne isocyanates in workplace air. When amines and aminoisocyanates are suspected to be emitted (e. g. from thermal degradation of PUR), it is recommended that, in addition to isocyanates, the amines and aminoisocyanates in the air are determined, using DBA and ethyl chloroformate as reagents (see ISO 17734 2). The method is suitable for the determination of a
