This part of ISO17734 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 ISO17734-1).

The method can be used for simultaneous determinations of amines, such as 4,4\'-methylenediphenyldiamine (4,4\'-MDA), 2,4- and 2,6-toluenediamine (2,4- and 2,6-TDA), and 1,6-hexamethylenediamine (1,6-HDA), and compounds containing both isocyanate and amine groups, such as 4,4\'-methylenediphenyl aminoisocyanate (4,4\'-MAI), 2,4-, 4,2-, and 2,6-toluene aminoisocyanate (2,4-, 4,2-, and 2,6-TAI), and 1,6-hexamethylene aminoisocyanate (1,6-HAI). The method is suitable for collecting amines and aminoisocyanates in both the gas and particle phases. The instrumental detection limit for the amines is about 5nmol/sample and for the aminoisocyanate, it is about 0,3nmol/sample. For a 15 l air sample, this corresponds to 0,4ng⋅m–3 for TDA and 0,03ng⋅m–3 for TAI.
