✦ Synopsis

Persilylated

fructose was separated into five components by means of gas chromatography.

Individual compounds were isolated with the help of micropreparative gas chromatography and characterized by infrared and mass spectroscopy. Components which, because of their small quantity and chemical lability, could not ,be isolated in this manner were investigated with the instrumental combination of gas chromatography and mass spectroscopy.

Of the five persilylated fructose derivatives two represent the pyranoside, two the furanoside and one the open-chain form.

## Abstract A method for structure determination of cyclic sulphides within mixtures is described. It involves the use of a vapour phase hydrodesulphurization micro‐reactor (Raney nickel) located between the chromatographic column and the mass spectrometer (hydrogen and deuterium are used as carrie
