DuraGuard Columns
Protect Sensitive Analytical Columns With Duraguard Columns, Effectively Extending Lifespan And Maintaining Efficiency.
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.
