INTRODUCTIONIn this method, microcolumns are prepared using any kind of chromatographic resin. The resin is held in place by making a constriction at the end of a GELoader pipette tip. Sample loading, washing, and elution are performed by loading liquid on top of the resin and applying air pressure to generate a low flow through the column. No frits are necessary.
