Agilent DB-17 30m, 0.32mm, 0.50u 123-1733

The Agilent DB-17 (catalog 123-1733) is a J&W capillary GC column 30 m long with a 0.32 mm inner diameter and a 0.50 µm film thickness. It uses a mid‑polarity DB-17 phase ((50%)-phenyl methylpolysiloxane) and is intended for gas chromatographic separations and confirmation analyses where slightly greater polarity than HP‑50+ is required. The column is bonded and crosslinked with a stated operating temperature range of about 40 °C to 280/300 °C and is supplied with a performance summary for quality verification.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.32 mm
• Film thickness: 0.50 µm
• Phase: DB-17 (50% phenyl methylpolysiloxane, mid polarity)
• Temperature range: 40 °C to 280/300 °C
• USP designation: G3 / G17

Advantages:

• Mid‑polarity DB-17 phase provides improved selectivity for confirmatory analyses compared with lower‑polarity phases.
• Bonded and crosslinked stationary phase that is solvent‑rinsible for easier maintenance and longer service life.
• Manufacturing quality control targets low column bleed and high sensitivity; each column ships with a performance summary for traceability and reproducibility.
