Agilent DB-5ms 30m 0.25mm, 0.25µm, DuraGuard 10m

Agilent DB-5ms GC Column, 30 m, 0.25 mm, 0.25 um, DuraGuard 10 m

Agilent J&W DB-5ms is a nonpolar phenyl arylene polymer, virtually equivalent to (5%-phenyl)-methylpolysiloxane, featuring an excellent signal-to-noise ratio for analytical applications. This improved performance gives better sensitivity and mass spectral integrity, and delivers excellent inertness with active compounds.

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.

This column is a close equivalent to USP phase G27, and is very low bleed, making it ideal for GC/MS.
