Agilent DB-1MS 30m, 0.32mm, 0.25u 123-0132

The Agilent (J&W) DB-1MS, catalog 123-0132, is a 30 m fused‑silica capillary GC column with a 0.32 mm inner diameter and a 0.25 µm DB-1ms (100% dimethylpolysiloxane) film. It is a low‑polarity, low‑bleed column produced for GC/MS and general‑purpose hydrocarbon separations. Typical uses include trace analysis by mass spectrometry and routine GC separations that require thermal stability over a wide temperature range.

Key Features:

• Length: 30 m
• Inner Diameter (ID): 0.32 mm
• Film Thickness: 0.25 µm
• Phase: DB-1ms (100% dimethylpolysiloxane)
• Capillary tubing: fused silica
• Format: 7 inch
• Temperature range: -60 °C to 340/360 °C

Advantages:

• Low column bleed optimized for GC/MS, improving sensitivity and cleaner mass spectra.
• Wide temperature range and thermal stability suitable for higher‑boiling analytes and demanding methods.
• Nonpolar DB‑1ms phase provides reliable, general‑purpose separations of hydrocarbons and volatile compounds.
• 7‑inch format and fused‑silica construction compatible with common Agilent GC systems and many other ovens.
