Abstract
A packing material for capillary electrophoresis comprises capillary electrophoresis in an apparatus having a capillary column, by charging a sample into an end of the capillary column and discharging the sample from the other end of the capillary column, is conducted using a capillary column prepared by packing the column with a packing material comprising glucomannan and then forming a gel in situ from the packed glucomannan. The packing material is packed into the capillary easily and forms a homogeneous gel therein which shows no damage by formation of bubbles and the like and thus can be utilized with stability, has superior health safety and is excellent with respect to biodegradation.
