Agilent DB-5MS 30m, 0.25mm, 0.25um 122-5532

The Agilent DB-5MS (catalog 122-5532) is a 30 m, 0.25 mm ID, 0.25 µm film capillary GC column with the DB-5ms stationary phase, designed for GC/MS applications. The nonpolar phenyl arylene (≈5% phenyl‑methylpolysiloxane) phase is manufactured for very low bleed and improved signal‑to‑noise, supporting better mass spectral integrity. It is intended for GC/MS separations such as aromatics, semi‑volatiles and other analyses that require inert, low‑bleed columns and compatibility with common environmental methods.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.25 mm
• Film thickness: 0.25 µm
• Phase: DB-5ms (≈5% phenyl‑methylpolysiloxane)
• Temperature range: -60 °C to 325/350 °C
• Format: 7 inch cage; Capillary tubing: fused silica

Advantages:

• Very low column bleed for improved GC/MS sensitivity and cleaner mass spectra
• High inertness with active compounds, yielding better peak shape and quantitative performance
• Bonded, crosslinked, solvent‑rinsible phase construction for robustness and reconditioning
• Broad operating temperature range suitable for environmental and semivolatile analyses
