Description for C18-Alkaline HPLC Column

The C18-Alkaline HPLC Columns packed by hydrophilic functional groups bonded silica(high purity) so as to realize hydrophilic features. Their selectivity for C18-Alkaline Columns is different from the traditional reversed-phase C18 HPLC Column. In order to avoid the reaction on the basis and silanol group, the hydrophilic functional groups replace most of the silanol group sites.
