  Thermospray ionization and tandem mass spectrometry of dyes

  摘要：

  AbstractSixteen 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‐activated dissociation experiments and by inspection of the chemistry of dye manufacture. Detection limits of 20–200 ng in the positive ion mode were obtained for seven dyes of the anthraquinone, triarylmethane, xanthene, coumarin, azo and sulfonated azo dye classes. Under conditions of negative ionization, detection limits for an anthraquinone dye and a sulfonated azo dye were about one order of magnitude higher.

  The present invention relates to highly compatible hydroxyphenyltriazine UV-absorbers and to their use in organic polymers, especially for protecting the contents of transparent plastic packages such as pharmaceuticals, cosmetics, personal care products, shampoos and the like, and especially foodstuffs such as beverages, fresh vegetables or meat, from the deleterious effects of ultraviolet radiation. Especially advantageous is the combined use of a UV absorber and an oxygen scavenger. It has been found that certain highly compatible tris-aryl-s-triazines are especially effective towards this end when incorporated in the containers or films in which such materials are stored.
