Title: Capillary column
Inventor: INOUE YOSHINORI
IPC: G01N27/447
Filed: 1987-02-27
Abstract: PURPOSE:To obtain a column which has a long life and excellent reproducibility of a sepn. characteristic by incorporating an alkyl group to the inside wall surface of a capillary column and sealing a methyl silicone polymer soln. and crosslinking agent soln. into the column to effect a crosslinking reaction so that a high-polymer film having a specified film thickness is coated on the inside wall surface. CONSTITUTION:An inert solvent in which an alkyl silane compd. is dissolved is passed in the capillary column and is brought into reaction with the silanol group on the inside wall surface of the column by which the alkyl group is incorporated into the inside wall surface. The soln. of the methyl silicone polymer and the crosslinking agent soln. are in succession sealed into the column and the end on one side of the column is kept sealed. The solvent evaporates and the thin film-like polymer is insolubilized while the crosslinking reaction progresses in the column when the capillary column is slowly wound in a thermostatic chamber subjected to nitrogen purging. The high-polymer film having the specified film thickness is coated on the inside wall surface of the column in such a manner. The sealing is thereafter removed and gaseous helium is passed in the column. The inside of the thermostatic chamber is maintained at the prescribed temp. and aging is executed for the specified time in this state.
