Investigation of N-alkylbenzamides by reversed-phase liquid chromatography

Characterization of calixarene‐bonded stationary phases

“…This equation has been widely used to describe the changes of the retention factor k with the methanol fraction of the mobile phase [13,[59][60][61][62][63][64][65][66][67]. It is correct for the majority of analytes in the range of 0.2-0.8 j, but for lower and higher concentrations often nonlinearity occurs [65,[68][69][70][71][72][73], for ionic solutes even at medium modifier concentrations [74][75][76].…”
