Esters are used instead of alkanes to evaluate the separation efficiency in the Grob Test, one check of a component in this process.  One typical component in them can be improved by using inert Silcosteel tubing to create micropacked columns that supposedly provide minimal peak tailing.  One method for injection in this procedure has the liner not get heated until the syringe is removed, at which point the column's temperature is raised to about 10 degrees below the boiling point of the solvent.  This mechanism works because different compounds have different partitioning behaviors when in the mobile phase compared to the stationary phase in the process.  FTP, identify this mechanism of separating organic compounds that often uses Helium in its mobile phase.
