Agilent DB-5 50m,.32mm-.52u 123-5056

This item is an Agilent DB-5 capillary gas chromatography (GC) column, phase: 5% phenyl-methylpolysiloxane (DB-5), supplied in a 7-inch cage format. It is a low-polarity fused‑silica capillary column designed for routine GC separations of volatile and semi-volatile compounds in analytical laboratories. Typical uses include general-purpose separations where a robust, thermally stable nonpolar phase is required.

Key Features:

• Phase: DB-5 (5% phenyl-methylpolysiloxane)
• Length: 50 m
• Inner Diameter (ID): 0.32 mm
• Film Thickness: 0.52 µm
• Format: 7 inch (cage)
• Temperature Range: -60 °C to 325/350 °C

Advantages:

• Low-polarity DB-5 phase offers broad applicability for nonpolar to moderately polar analytes, making it a general-purpose column.
• Thicker 0.52 µm film provides increased sample capacity and improved retention for semi-volatile or late-eluting compounds.
• Wide temperature range and bonded, cross-linked fused‑silica construction deliver thermal stability and low bleed for reliable high‑temperature analyses.
