Pre Clean ORG after high water concentration eluent flow

The data below is a chromatogram obtained by repeating the analysis of nucleic acid bases and nucleotides using an ODS column. With Pre Clean ORG, there is little change after 400 hours, but the peak shape worsens after about 100 hours if it is not used. Pre Clean ORG, which flows through the aqueous solution as shown in the photograph, is dirty and prevents contamination of the column.
