Agilent DB-17MS 30m, 0.25mm, 0.25u 122-4732

The Agilent DB-17MS (part number 122-4732) is a 30 m fused‑silica capillary GC column with a DB-17ms mid‑polarity stationary phase designed for GC/MS applications. It is a low‑bleed, (50%‑phenyl) methylpolysiloxane‑equivalent column intended to provide inert, reproducible separations for semivolatiles and active compounds in routine and mass‑spectrometry–based analyses. Typical uses include pesticide and semi‑volatile compound analysis and other GC/MS workflows requiring enhanced mass spectral integrity.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.25 mm
• Film thickness: 0.25 µm
• Phase: DB-17ms (mid polarity, ~50% phenyl methylpolysiloxane equivalent)
• Capillary tubing: fused silica
• Temperature range: 40 °C to 320/340 °C

Advantages:

• Very low column bleed suitable for GC/MS, improving sensitivity and baseline stability.
• Excellent inertness for active compounds, reducing adsorption and improving peak shape for semivolatiles and pesticides.
• Bonded, cross‑linked, and solvent‑rinsable construction for robustness and extended column life.
• High maximum operating temperature (up to ~320/340 °C) enables high‑temperature separations and broad analyte scope.
