PURPOSE:To prevent increase in cost as caused by consumption of a capillary column by providing a solid phase on an internal surface of a part except for near both ends of a quartz glass capillary column. CONSTITUTION:In order to form a solid phase 3 except for a terminal 24 of a quartz glass capillary 1, for example, the quartz glass capillary 1 is filled with a solution of a solid phase 3 forming material over the entire length thereof and a solvent is evaporated at a relatively low temperature by a static method to form a layer of the solid phase 3 forming material over the entire length of the quartz glass capillary 1. Then, the solid phase 3 forming material is crosslinked by heating a part alone to form the solid phase 3 or by irradiating it with an electron beam, gamma rays or the like and the solid phase 3 forming material yet to be crosslinked is eluted by a proper solvent. In the crosslinking by heating, an isolated group forming agent to the solution of the solid phase 3 forming material is added beforehand and heated above a temperature at which the isolated group is generated. |
