Guard-Disc® Protection System
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.
