The application of the extended thermodynamic approach to describe the effect of counterions, both of chaotropic agents and ionic strength modifiers, on the retention behavior of protonated basic analytes in chaotropic chromatography [PDF]

open access: yesArhiv za farmaciju
In this study, the extended thermodynamic approach was used to quantitatively explain the effect of counterions, both of chaotropic agents and ionic strength modifiers, in variable (vI) and constant ionic strength (cI) systems on the retention behavior ...

Retention of Anions on Silica-based Metalloporphyrin Stationary Phases

open access: yesAnalytical Sciences, 2002
The silica-based Fe(III)-protoporphyrin and Zn-tetraphenylporphyrin stationary phases were examined for the HPLC separation of anions. The retention of nine common inorganic anions as well as benzoate anion (BA) and its hydroxy analogues (HBA) was examined using tartrate, acetate, and succinate eluents.
