Glucose, cellobiose, lactose and raffinose used as chiral stationary phases in HPLC

This paper presents the enantioseparation using glucose, cellobiose, lactose and raffinose as chiral selector bonded to silica gel via an arm in HPLC. Surprisingly, they also possess high enantioseparation selectivity, may be used in normal-phase and reversed-phase mode, and there is a big chiral discriminating complementary. This work indicates that oligosaccharides could soon become very attractive as a new class of chiral stationary phase for HPLC.

Influence of mobile phase acid-base equilibria on the chromatographic behaviour of protolytic compounds

A review about the influence of mobile phase acid-base equilibria on the liquid chromatography retention of protolytic analytes with acid-base properties is presented. The general equations that relate retention to mobile phase pH are derived and the different procedures to measure the pH of the mobile phase are explained. These procedures lead to different pH scales and the relationships between these scales are presented. IUPAC rules for nomenclature of the different pH are also presented. Proposed literature buffers for pH standardization in chromatographic mobile phases are reviewed too. Since relationships between analyte retention and mobile phase pH depends also on the pKa value of the analyte, the solute pKa data in water-organic solvent mixtures more commonly used as chromatographic mobile phase are also reviewed. The solvent properties that produce variation of the pKa values with solvent composition are discussed. Chromatographic examples of the results obtained with the different procedures for pH measurement are presented too. Application to the determination of aqueous pKa values from chromatographic retention data is also critically discussed.

The correlation and prediction of infinite dilution activity coefficients of compounds in water at 298.15 K

We have assembled infinite dilution activity coefficients in water at 298 K for 661 varied compounds. For 655 of these compounds we were able to construct a multiple linear regression equation using Abraham descriptors with a standard deviation of 0.29 log units in log gamma?. Unlike methods such as ASOG or UNIFAC, our equation does not rely on functional groups, and so we can predict further values of activity coefficients for compounds with functional groups not included in the 655 data base. These include ferrocene, terpenes such as alpha-pinene, and compounds containing phosphorous atoms such as trimethylphosphate and dibutylphosphinic acid.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.
