C18 Alkaline HPLC Column
Description
Description of Alkaline C18 Silica Gel HPLC Column
The C18 alkaline column is a new generation of different selective C18 silica gel HPLC column developed by Hawach. It has a hydrophilic group embedded in it to make it hydrophilic. The hydrophilic group replaces a large amount of silicon.
This HPLC column is widely used for basic compounds. 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 Alkaline C18 HPLC Column
- Octadecylsilyl silica gel HPLC column
- Relatively weaker polarity than the C8 HPLC column
- 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.
