Agilent DB-624 30m, 0.25mm, 1.40u 122-1334

The Agilent J&W DB-624 column (catalog 122-1334) is a fused‑silica capillary GC column with a mid‑polar DB-624 stationary phase formulated for volatile organic compound and residual solvent analysis by GC and GC/MS. The standard 30 m × 0.25 mm, 1.40 µm configuration is supplied by the manufacturer for fast GC/MS screening and is explicitly recommended for EPA and related environmental/industrial methods. It serves as an analytical replacement for HP-624 and is used where reliable separation of low‑molecular‑weight volatiles and priority pollutants is required.

Key Features:

• Length: 30 m
• Inner Diameter (ID): 0.25 mm
• Film thickness: 1.40 µm
• Phase: DB-624 (mid‑polar; 6% cyanopropylphenyl / 94% dimethylpolysiloxane)
• Temperature range: -20 °C to 260 °C
• USP designation: G43

Advantages:

• Manufacturer‑recommended for EPA and related methods and optimized for fast GC/MS analysis of volatile priority pollutants and residual solvents.
• Bonded, crosslinked, and solvent‑rinsable stationary phase with rigorous QC for low column bleed, high sensitivity, and consistent efficiency.
• Excellent inertness and peak shape for active, low‑molecular‑weight compounds—supports improved signal‑to‑noise and quantitative performance.
