DuraGuard Columns, Agilent Technologies

Chromatography Columns

Constructed with integral deactivated fused silica tubing that minimizes front-end contamination and reduces connection problems associated with union connections.

DuraGuard and EZ-Guard columns with ‘built-in’ guard columns, no press-fit connectors
Minimizes front-end contamination and increase column life
Aids in focusing sample onto the front of the column for better peak shape
Minimizes MSD contamination originating from the column (when used as transfer line to the MS detector)
Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency
Performance Summary shipped with each column

Deactivated fused silica tubing is commonly added to the front of an analytical column to act as a guard. Improper installation can lead to issues, peak shape problems, and leaks associated with unions. To eliminate these problems, Agilent J&W DuraGuard columns are made with a single, continuous piece of tubing, consisting of a built-in length of deactivated fused silica tubing and an analytical column. Difficult samples, such as pesticides or drugs, can be analyzed without any undesirable contributions from the unions.
