Agilent DB-23 30m, 0.25mm, 0.25u 122-2332

The Agilent DB-23 (part number 122-2332) is a 30 m, 0.25 mm ID fused‑silica capillary GC column with a 0.25 µm film thickness, built on the DB-23 stationary phase ((50%-cyanopropyl)-methylpolysiloxane). According to Agilent and authorized distributors, it is a high‑polarity, bonded and cross‑linked column specifically designed for high‑quality separation of fatty acid methyl esters (FAMEs), including resolution of cis/trans isomers. The column is solvent‑rinsable, equivalent to USP phase G5, and intended for routine analytical GC methods that require reliable FAME separations.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.25 mm
• Film thickness: 0.25 µm
• Stationary phase: DB-23 ((50%-cyanopropyl)-methylpolysiloxane)
• Capillary tubing: fused silica
• Operating temperature range: 40 °C to 250/260 °C
• USP designation: G5

Advantages:

• Optimized for FAME analysis — excellent resolution of cis‑ and trans‑FAME isomers (manufacturer claim).
• Bonded, cross‑linked and solvent‑rinsable construction for durability and cleaning between runs.
• Broad operating temperature range supports diverse GC methods and reliable performance up to ~250/260 °C.
• USP G5 equivalence ensures compatibility with methods and regulatory workflows that reference that phase.
