Biological monitoring of hexamethylene diisocyanate by determination of 1,6-hexamethylene diamine as the trifluoroethyl chloroformate derivative using capillary gas chromatography with thermoionic and selective-ion monitoring.
Biological monitoring of isocyanates and related amines
TLDR
There was a considerable inter-individual variation in the excreted amounts, but the intra-Individual variation inThe excretion of HDA was limited, and the subjects N-acetylator phenotype was determined by a dapsone test.
Evaluation of Chromatographic Methods for the Determination of Isocyanates in Air
Abstract Chromatographic methods for the determination of toluene diisocyanates (TDI) in air, at concentrations of 20–40μg/m3, were evaluated. Test atmospheres were generated by a gas-phase…

Determination of isocyanates, aminoisocyanates and amines in air formed during the thermal degradation of polyurethane.
TLDR
An air sampling method based on the collection of air samples using impinger flasks containing di-n-butylamine in toluene with a glass fibre filter makes it possible to sample and determine amines and aminoisocyanates, in addition to isocyanate.
Biological monitoring of isocyanates and related amines
TLDR
Two men were exposed to toluene diisocyanate (TDI) atmospheres at three different air concentrations by a gas-phase permeation method, and the exposures were performed in an 8-m3 stainless-steel test chamber, and a connection was observed between concentrations of 2,4- and 2,6-TDI in air and the levels of 1,2- and 1,3-TDA in plasma.
