For protection of your main HPLC column from contamination, it is recommended to use guard columns. These short columns are placed into a guard column holder. The guard column holder in combination with a guard column inside is installed between the injector and the HPLC column. This installation prevents chemical impurities to reach the main column. Because a contamination could form an irreversible bond with the column packing material (stationary phase) and this can result in shorter column life. If you want to prolong the lifetime of your main column, then these short columns can help you.

The ideal phase for overall sophisticated analytical separations

This high density phase with its endcapping suppresses any unwanted polar interactions between the silica surface and the sample, which makes “Gravity” particularly suitable for the separation of basic and other ionizable analytes.

Properties:

• Suitable for LC/MS and HPLC at pH extremes (pH 1-11)
• Ideal for method development
• Superior base deactivation
• Multi-Endcapping

Recommended application(s):

• In general, compounds with ionisable functional groups such as basic pharmaceuticals and pesticides e.g. analgesics, anti-inflammatories, antidepressants, herbicides, phytopharmaceuticals, immunosuppressants.
• USP L1 (C₁₈) · USP L7 (C₈)
