Effect of a modifying cobalt(II) chloride additive on the selectivity of adsorbents and liquid stationary phases used in gas chromatography for the separation of volatile organic substances (VOSs) of different chemical nature is considered. It is found that the specified additive leads to a drastic increase in the retention parameters of oxygen-containing VOSs, first of all, aliphatic alcohols, and relatively weakly affects the retention of other VOSs, including nucleophilic nitrogen-containing compounds. In particular, the addition of cobalt chloride to Carbowax increases the retention parameters of methanol and ethanol and reduces the corresponding parameters for analytes from the other VOS classes.
