## Abstract Fused silica capillary columns of 0.250βmm i.d., packed with 5βΞΌm particles of nonpolar (octadecyl, octyl, and butyl) and polar (silica, diol, cyano, and amino) materials, have been prepared using a dryβpacking technique. The performance of the columns has been evaluated using the reduc
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
