Guard-Disc® Protection System

Guard Disc and Holder with Column
Guard-Disc System

The Transgenomic Guard-Disc System is a patented column protection system that is designed to provide the protection capabilities of a guard column without adding any extra volume that might interfere with chromatographic separation.

The Guard-Disc System is comprised of a disc, which is available in a variety of functionalities, and a disc holder that couples directly to the column.

The disc is a PEEK ring that contains a functionalized chromatographic membrane.This chromatographic membrane is available in a variety of stationary phases for both HPLC and Ion Chromatography applications.

Phases

The stationary phases that Guard-Discs Systems are available in include:

  • C18
  • C8
  • Styrene/DVB
  • Anion Exchange
  • Cation Exchange

It is these functional groups that bind the contaminants that would otherwise be trapped on your analytical column.

Double Protection

Transgenomic Guard-Disc Systems are porous as well. Not only do they bind species that may contaminate your analytical column, they also filter out particulates that would otherwise be trapped on your analytical column. The Transgenomic Guard-Disc System provides double protection for your chromatographic column.
