Abstract: Columns, packed with 10 μm diameter porous silica particles (15 nm diameter pores) containing polydimethylsiloxane (20%, w/w) or polymethyloctylsiloxane (40%, w/w) sorbed into the pores, were tested for chromatographic stability as a function of elution volume. No significant changes in efficiency, retention factor or separation factor were observed following extended washing (up to 5000 column volumes) of either stationary phase with methanol-water mobile phases. © 1995 Elsevier Science B.V.
