Summary
Two columns in parallel are used for the separation of C1−C10 hydrocarbons: a SCOT column coated with Apiezon L and a packed column containing 2 m Durapak (phenylisocyanate/Porasil C) and 3 m 25% squalane on Gas Chrom P. The separation efficiency of the combined packed column is demonstrated by the analysis of radiolytic products of n-pentane. Special attention was given to the separation of pentenes and to their separation from the solvent peak (n-pentane). The effect of temperature on the individual separations as well as the optimal experimental conditions for the C1−C10 hydrocarbon separation are discussed. Relative retention times of the C1−C6 saturated as well as the unsaturated hydrocarbons on the combined packed column are presented.
