## Abstract This review article summarizes the variety of polar stationary phases that have been employed for capillary electrochromatographic separations. Compared with reversedβphase stationary phases, the polar alternatives provide a completely different retention selectivity towards polar and c

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
## Abstract Whereas the immobilization of apolar silicone phases is essentially understood and mastered, the corresponding treatment of even moderately polar phases remains problematical. Upon attack by peroxide radicals, these phases respond by forming active transformation products rather than by
