ABSTRACT:
Deterioration of performance of a separation column for liquid chromatograph due to changes in the functional groups during the preservation or application is prevented by filling a solution containing a component in the molecule with the same structure as that of the chemical function group of a packing material for the separation column as a filling liquid together with the packing material in the separation column, and also by washing the separation column with the same filling liquid as a washing solution after the analysis and retaining the washing solution therein, whereby the preservation stability of the separation column is improved and the separation column can be preserved at room temperature.
