Brief analysis of the retention process in RP-HPLC systems with a C(30) bonded stationary phase.
The influence of the mobile-phase composition on the retention of eight model substances in different RP-HPLC systems with a C(30) alkyl bonded stationary phase has been studied. The aim of this study was to compare the performance of four valuable retention models assuming the partition and adsorption mechanism of retention. All the models were verified for different experimental data by four criteria: the sum of squared differences between the experimental and theoretical data; the approximation of the standard deviation; the Fisher test; and the F-test ratio.
