Abstract
The air contaminants are absorbed in a mixture of hydrochloric acid/acetic acid/water, the solution made basic, and the analytes extracted (as the corresponding diamine in the case of TDI). The trifluoroacetamide derivatives are then formed and measured by gasliquid chromatography.This publication has 2 references indexed in Scilit:
