โœฆ Synopsis

Trace analysis of alkylbenzenesulphonates in river water has been itivestigated by combined gas-liquid chromatography-mass spectrometry. Methylene blue-alkylbenzenesulphonate complexes are first formed and then extracted with chloroform. The methylene blue is removed and the alkylbenzenesulphonates are converted to methyl sulphonate derivatives by treatment with phosphorus pentachloride and then with methanol. The individual components of the alkylbenzenesulphonate are determined separately by mass fragmentography. The reproducibility of the determination is satisfactory.

A method is described for the identification of anthocyanidins by gas-liquid chromatography and mass spectrometry. Anthocyanidins, when treated with trimethylchlorosiiane and hexamethyldisilazme, yield volatile compounds whose nature is discussed on the basis of their high-resolution mass spectra, o
