A GC-MS method is developed for structure determination of aliphatic within mixtures. It involves online application of a gas-phase dehydrogenation reaction after GC separation and before MS analysis. Primary and secondary alcohols are converted into corresponding aldehydes and ketones while tertiary alcohols under reaction conditions (Cu, 300oC). Analysis of EI spectra of alcohols and carbonyl compounds leads to reliable determination of molecular ions of initial alcohols, location of hydroxyl groups and determination of branching at β-carbon atom.
