✦ Synopsis
Fused silica-packed capillary columns containing vancomycin immobilized by reductive amination on an aldehyde-silica were used to separate enantiomers of some non-steroidal anti-inflammatory drugs. Attempts have been made to qualitatively explain the influence of various mobile phase compositions on the enantioselective retention. The effects of mobile phase pH, buffer, and organic modifier concentrations were investigated as well as the influence of salts of hydrophobic ions added to the mobile phase to induce ion pair retention.

Vancomycin immobilized on an aldehyde functionalized silica support in packed capillary columns has been used as a chiral stationary phase in supercritical fluid chromatography under subcritical conditions. The use of carbon dioxide with methanol as the mobile phase modifier is shown to offer an ext
Vancomycin selectively immobilized to silica via either one of its two amino groups has been investigated and compared with columns made from native vancomycin. The chemical modification of vancomycin prior to immobilization involved protection of one amino group as a 9-fluorenylmethyl carbamate. Th
