The chemical ionization mass spectra of cyclic glycols and mono‐ and di‐saccharides using trimethyl borate as reagent gas have been studied. In the gas phase, the trimethyl borate ions react stereospecifically with molecules of cis ‐cyclic glycols to form characteristic ions, from which the stereochemical isomers of 1,2‐cyclopentanediols, 1,2‐cyclohexanediols and mono‐ and di‐saccharides can be definitely distinguished.
