Coated and Immobilized Polysaccharides‐Based Stationary Phases for Planar Metallocenes Enantioseparation in Liquid Chromatography

ELECTROPHORESIS, EarlyView.
This study examined 21 new ferrocene and ruthenocene derivatives, including those with planar and central chirality. Their stereochemical behavior was examined using UV‐detected normal‐phase liquid chromatography. Under fixed conditions, eight polysaccharide‐based chiral stationary phases were tested using n‐heptane combined with either 2‐propanol or ...

Coupling of Supercritical Fluid Extraction with Chromatography

Analytical Sciences, 1991
Coupling methods between supercritical fluid extraction (SFE) and various chromatographic techniques have been reviewed. Developments using supercritical fluids in chromatography have been tremendous and a confirmation of the usefulness of this technique (called supercritical fluid chromatography (SFC)) has been evidenced by many scientists.
