Agilent DB-1MS Ultra Inert 30m, 0.32mm, 0.25um 123-0132UI

The Agilent DB-1ms Ultra Inert (part number 123-0132UI) is a low-polarity fused‑silica capillary GC column in the DB-1ms Ultra Inert phase designed for gas chromatography–mass spectrometry. It is 30 m long with a 0.32 mm internal diameter and a 0.25 µm film thickness, optimized to deliver low column bleed and high signal-to-noise for MS detection. Manufacturer and authorized distributors state the column provides consistent column inertness, excellent peak shapes for challenging active analytes, and is individually tested and shipped with a performance summary.

Key Features:

• Length: 30 m
• Inner Diameter (ID): 0.32 mm
• Film Thickness: 0.25 µm
• Phase: DB-1ms Ultra Inert (low polarity)
• Capillary tubing: fused silica
• Format: 7 inch
• Temperature range: -60 °C to 340/360 °C

Advantages:

• Ultra-inert surface minimizes adsorption and degradation of active analytes, improving peak shape.
• Low column bleed and MS-optimized construction enhance sensitivity and signal-to-noise in GC–MS.
• Each column is individually tested and shipped with a performance summary to support lot-to-lot consistency.
• Wide operating temperature limits support a broad range of GC methods and analyte volatilities.
