| Abstract: | Sol-gel capillary column for gas chromatography was prepared with Hydroxyl-Terminated β-cyan-ethyl methyl-Polysiloxane as stationary phase.On this column alkanes,aromatic compounds,amines,alcohols etc.were separated successfully,although the length of this column was only 2.5m.Experiments showed that the column-inertness was good and the unsymmetrical factor was 1.At high temperatures the stationary phase of the column showed excellent stability.Results showed that the relative standard deviation of the retention time was less than 0.46%.The stationary phase showed higher polarity because of the introduction of the cyan groups and the hydroxyl-termination. |
