Abstract

Abstract Sixteen commercial dye samples and three liquid wastes from organic pigment and dye manufacture have been characterized without prior chromatography by thermospray ionization and low energy collision-activated dissociation of protonated molecules using a triple quadrupole mass spectrometer. Many samples contained precursors of the dyes and other by-products of the synthesis. Many of these components were identified by collision- ...
