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.
