    The effect of conductivity tuning in chiral separations by CE; Using hydroxypropyl-β-cyclodextrin in combination with tetraalkylammonium ions

    Different approaches how to handle the electromigration dispersion process that occurs in separation and determination of enantiomers are presented. The use of cyclodextrins as chiral selectors in resolution e...

    Tartaric acid derivatives as chiral selectors in liquid chromatography

    Direct separation of enantiomeric amino-alcohols using tartaric acid derivatives as chiral complexing agents in organic stationary or mobile phases is described. Among the tartaric acid derivatives studied, on...

    Ion-pair chromatography with divalent counter cations in reversed-phase systems

    The chromatographic behaviour of naphthalenedisulfonates when using divalent alkylammonium ions as counter ions in a phosphate buffered mobile phase has been studied. The retention of the disulfonates was foun...

    Adsorption of polar solutes in reversed-phase liquid-liquid chromatography

    The properties of chloroform as a liquid stationary phase in reversed-phase liquid chromatography have been investigated. Stable systems and complete pore filling of the support were obtained. Uncharged acids ...

    Chiral separation of aminoalcohols by ion-pair chromatography

    A new chiral counter ion, N-benzoxycarbonyl-glycyl-L-proline (ZGP), added to the organic mobile phase (dichloromethane) has been used for separation of enantiomers of aminoalcohols with LiChrosorb DIOL as the ...

    Chiral resolution of aminoalcohols by ion-pair chromatography

    Chiral resolution of aminoalcohols is performed by ionpair chromatography using (+)-10-camphorsulphonic acid in methylene chloride + 1-pentanol (199∶1) as mobile phase and LiChrosorb DIOL as adsorbing stationa...
