Mechanistic aspects of chiral discrimination on modified cellulose.
Cellulose and cellulose derivatives are biopolymers which are often used as stationary phases for the separation of enantiomers. Describing the mechanism of such separations is a difficult task due… Expand
Separation of enantiomers by gas liquid chromatography with an optically active stationary phase
Hydrophilic shielding of hydrophobic, cation- and anion-exchange phases for separation of small analytes: direct injection of biological fluids onto high-performance liquid chromatographic columns.
Shielded hydrophobic phases (SHPs) have an external hydrophilic network that prevents larger protein molecules from interacting with hydrophobic zones. Smaller analytes are not sterically hindered… Expand
Chiral separation of heterocyclic drugs by HPLC: solute-stationary phase base-pair interactions
Wide-pore silica-based ether-bonded phases for separation of proteins by high-performance hydrophobic-interaction and size-exclusion chromatography.
This paper examines the use of wide-pore silica-based hydrophilic ether-bonded phases for the chromatographic separation of proteins under mild elution conditions. In particular, ether phases of the… Expand

The applicability of high-performance hydrophobic interaction chromatography using newly developed silica-based ether-bonded phases is demonstrated in the purification of the rat liver enzymes… Expand
Interaction between asymmetric solutes and solvents. Peptide derivatives as stationary phases in gas liquid partition chromatography.
Abstract Structural considerations leading to the development of efficient optically active stationary phases for the separation of enantiomers by gas chromatography are presented. The phases which… Expand

High-performance separations of proteins, based on immobilized-metal affinity chromatography (HPIMAC), are described. The stationary phase consisted of iminodiacetic acid (IDA) chelate groups, bonded… Expand
9-Fluoreneacetyl-tagged, solid-phase reagent for derivatization in direct plasma injection.
We describe here a resin-based derivatization reagent, containing a 9-fluoreneacetyl tag on a controlled-pore substrate, for direct injection analysis of amphetamine in plasma. On-line, pre-column… Expand
