ABSTRACT
It was shown (see, e.g., Refs. 35 and 70) that the dependence of retention data on the amount of stationary liquid phase (or proportional it value) in the column can be reduced significantly for polar stationary phases of n-alkanes with a series of other compounds that are readily soluble in the stationary phase; also, the precision of determination of invariant Kovats indexes and relative retention values (see, e.g., Table 9 [70]). The application of 1-alkenes (as standard) made it possible to improve the reproducibility of 10 values and to reduce the values 2-50-fold in the former instance and 3-70-fold in the latter.
