Determination of organonitrogen compounds in air using liquid chromatography and mass spectrometry — Part 2: Amines and aminoisocyanates using dibutylamine and ethyl chloroformate derivatives
ISO 17734-2:2013 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-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 5 nmol/sample and for the aminoisocyanate, it is about 0,3 nmol/sample. For a 15 l air sample, this corresponds to 0,4 ng⋅m?3 for TDA and 0,03 ng⋅m?3 for TAI.

Določevanje organskih dušikovih spojin v zraku s tekočinsko kromatografijo in masno spektrometrijo - 2. del: Določevanje aminov in aminoizocianatov preko derivatov dibutilamina in etilkloroformiata
Ta del standarda ISO 17734 podaja splošne napotke za vzorčenje in analizo aminov ter aminoizocianatov v zraku na delovnem mestu. Zelo se priporoča, da se določevanje aminov in aminoizocianatov izvaja skupaj z določevanjem izocianatov v zraku, pri čemer se za reagent uporablja DBA
(glej ISO 17734-1).
Metodo je mogoče uporabiti za hkratno določevanje aminov, kot so 4,4'-metilendifenildiamin
(4,4'-MDA), 2,4- in 2,6-toluendiamin (2,4-, 2,6-TDA) in 1,6-heksametilendiamin (1,6-HDA), ter spojin, ki vsebujejo skupine izocianatov in aminov, kot so 4,4'-metilendifenil aminoizocianat (4,4'-MAI), 2,4-, 4,2- in 2,6-toluen aminoizocianat (2,4, 4,2, 2,6-TAI), 1,6-heksametilen aminoizocianat (1,6-HAI). Metoda je ustrezna za zbiranje aminov in aminoizocianatov v plinski fazi in fazi delcev. Meja detekcije instrumentov za amine je približno 5 nmol/vzorec, za aminoizocianate pa 0,3 nmol/vzorec. For a 15 l air sample, this corresponds to 0,4 ng⋅m–3 for TDA and 0,03 ng⋅m–3 for TAI.
