β¦ Synopsis
Column chromatography of visual pigments on controlled-pore glass beads run at high pressure offers rapid, high-resolution analytical and preparative separations at room temperature. Low-temperature chromatography shows serious adsorption. Rapid elution and recycle methods add to the technique's versatility.

Sugars were separated gas chromatographically on short apolar glass capillary columns by using cold, on-column injection (OCI) techniques. After silylation, oligomers up to the hexasaccharides could be efficiently separated in reasonable retention times. Response factors of silylated sugars were det
Chemically bonded phases on controlled pore glass substrates have been prepared by the condensation of 3-(2-aminoethylamino)propyltrimethoxysilane in anhydrous or aqueous media. Sorption of copper(II) by the chemically bonded phase was measured via potentiometry and can be described by pseudo-second
