Gas chromatographic separation and automatic identification of complex mixtures of organic solvents in industrial wastes

The analysis of complex mixtures of industrial solvents in chemical wastes was carried out by the simultaneous use of non-polar and polar wide-bore capillary or packed columns. The co-eluting peaks on one of the two phases were resolved on the other phase, and the identification and quantitative ana...

Description
Summary:The analysis of complex mixtures of industrial solvents in chemical wastes was carried out by the simultaneous use of non-polar and polar wide-bore capillary or packed columns. The co-eluting peaks on one of the two phases were resolved on the other phase, and the identification and quantitative analysis of mixtures containing up to 32 compounds was possible. Some integrators and data collectors were tested to allow the automatic identification of the compounds by comparing the chromatograms obtained from a 50:50 split of the sample into two parallel columns connected to identical flame ionization detectors.
