Capillary gas chromatographic separations of a multi-component mixture of polyalcohol compounds

Capillary gas chromatographic separation conditions were established for a 31-component mixture of polyhydroxy compounds containing two tetritols, three pentitols, six hexitols, seven monoanhydropentitols, eight monoanhydrohexitols, three dianhydrohexitols, pentaerythritol and myoinositol. Mixtures of per-O-acetyl or per-O-trimethylsilyl derivatives of these compounds were separated on fused-silica columns using highly polar DB-23 and non-polar HP-5 stationary phases, respectively. Relative retention times for each compound with respect to pentaerythritol and myoinositol and methylene units were determined.
