PROCESS FOR PREPARING A CAPILLARY COLUMN EMPLOYED BY A POLYMERIZATION GEL FORMED IN THE SPACE USING A MIGRANT STARTER

摘要

P Process for preparing a capillary column filled with a gel formed by space-progressing polymerization using a migrating initiator. BR/ In a capillary tube (11), previously filled with a monomer, a crosslinking agent and a catalyst, between ends (12, 13) immersed in reservoirs (14, 15) surrounding a electrode (16, 17) is passed (with a source (18) of energy) a charged initiator for the polymerization. The speed of movement of the initiator is low enough to maintain a sharp leading edge, which causes a progressive polymerization from one end of the capillary to the other. This avoids shrinkage and discontinuity of the gel. BR/ Application: electro-analysis of small samples by electrophoresis. / P
