PURPOSE:To reduce the analysis time with a higher heat resistance,by providing a metal cover layer on the surface of a capillary tube comprising quartz or melt silica. CONSTITUTION:An aluminum coating layer 2 is provided on a melt silica layer (capillary) 1a and a stationary phase 3 inside a melt silica layer 1. This capillary column will pose problem in application even above 500 deg.C. The column according to this invention also will not break by normal handling and provides improved conductivity because of the aluminum coating layer along with better stability. For example, this can reduce the required analysis time by about 30% as compared with the distribution by the capillary column using the conventional high molecular material film. |
