Agilent DB-17 30m,.53mm-.25u 125-1731

The Agilent DB-17 (catalog 125-1731) is a fused‑silica gas chromatography capillary column with a mid‑polarity (50% phenyl‑methylpolysiloxane) stationary phase. It is supplied as a 30 m, 0.53 mm i.d. column with a 0.25 µm film and is manufactured for routine and confirmation analyses of mid‑polar analytes. The column is intended for use in GC methods requiring USP G3/G17 phase equivalence and reliable chromatographic performance.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.53 mm
• Film thickness: 0.25 µm
• Phase: DB‑17 (50% phenyl‑methylpolysiloxane)
• Capillary tubing: fused silica; format: 7‑inch
• Operating temperature range: 40 °C to ~260/280 °C

Advantages:

• Mid‑polarity DB‑17 phase suited for confirmation and separation of moderately polar compounds (USP G3 equivalence).
• Bonded, crosslinked stationary phase that is solvent‑rinsible for cleaning and extended column life.
• Manufacturing QC for low bleed, sensitivity, and efficiency provides reproducible performance for routine and confirmatory GC analyses.
• Large 0.53 mm i.d. with 0.25 µm film offers higher sample capacity for trace or dilute sample applications.
