ABSTRACT:
The present invention provides a stable stationary phase for chromatography which comprises porous ZrO.sub.2 spherules coated with a cross-linked polymer coating wherein said coated spherules have a pore size from about 20-500 .ANG. and a particle diameter range of about 0.5-500 microns, and are stable in basic media to pHs of up to about 14.
