On a combined gas chromatograph-mass spectrometer (GC-MS), a series of isomeric tricosanols and their trimethylsilyl derivatives has been measured and the dependence of fragmentation on the position of the hydroxylic group has been examined. In addition to the known a and b ions resulting by the ct-and~-cleavage, there have been identified aI, bI, a-2, c-2, and d-2 ions corresponding to the elimination of one or two hydrogens from products ...
