US 2017/0291158 A1 · Sol-Gel Polymeric Stationary Phases for High-Performance Liquid Chromatography and Solid Phase Extraction: Their Method of Making

Abstract

A sol-gel sorbent or chromatography stationary phase is a particulate metal oxide gel containing polymeric segments uniformly distributed throughout the metal oxide gel. The metal oxide gel is an oxide from silicone or other metal oxide that can have one of the valence bonds attached to an organic group and the remainder occupied by oxygens that can be provided as an oxide or an alkoxide or aryl oxide of the polymeric segments. The particles are used for an SPE sorbent or as a packing for a reversed phase high-performance liquid chromatography (RP-HPLC), a normal phase high-performance liquid chromatography (NP-HPLC) column or a hydrophilic interaction liquid chromatography (HILIC) column.
