Retention Indices of 55 Solutes Belonging to Eight Monofunctional Groups Homologous Series on 14 Chromatographic Capillary Columns

Retention indices, RI, of 55 solutes belonging to eight chemical monofunctional group series were computed at 373 K from retention factors measurements on 14 capillary columns coated with stationary phases, SP, spanning almost the whole polarity range. RI-values of some of these analytes were valida...

Description
Summary:Retention indices, RI, of 55 solutes belonging to eight chemical monofunctional group series were computed at 373 K from retention factors measurements on 14 capillary columns coated with stationary phases, SP, spanning almost the whole polarity range. RI-values of some of these analytes were validated by comparison with literature values. Positive slope straight lines were obtained for the isothermal RI versus Z plots for the eight chemical functions. For a given series the slope (A) is rather insensitive to RP, while the intercept (FF) clearly increases linearly with increasing RP. For a given stationary phase A does not show any clear trend with increasing solute polarity, while FF increases clearly from the less polar to the most polar series.
