Description of C18 Alkaline HPLC Columns

The C18-Alkaline HPLC columns are a new generation of different selective C18 developed by Hawach. It has hydrophobic interaction and electrostatic interaction. It has a hydrophilic group embedded in it to make it hydrophilic. The hydrophilic group replaces a large amount of silicon. The alcohol-based site can effectively prevent the interaction between the alkaloid and the silanol group, and the alkaline substance has a good peak shape.

Characteristics of C18 Alkaline HPLC Columns

The peak shape of the alkaline substance is better, and the material having a poor peak shape on the conventional double-sealed C18 has a better peak shape;
The rapid separation of similar samples by the mobile phase is hydrophilic, and the mobile phase of the high water ratio can be used, which is extremely stable.
