ISO 17734-2-2013 在空气中用液相色谱法和质谱学对有机氮化合物的测定.第2部分:用二丁胺和乙基氯甲酸酯衍生物的胺和氨基异氰酸酯
Determination of organonitrogen compounds in air using liquid chromatography and mass spectrometry.Part 2: Amines and aminoisocyanates using dibutylamine and ethyl chloroformate derivatives
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).
