Agilent ULTRA-2 50m, 0.20mm, 0.33u 19091B-105

Agilent ULTRA-2 50 m, 0.20 mm, 0.33 µm (19091B-105) is a fused-silica capillary gas chromatography column with the Ultra 2 low-polarity stationary phase. It provides a 50 meter column length with 0.20 mm inner diameter and 0.33 µm film thickness for routine GC separations and GC/MS analyses. The column is specified with a temperature range of -60 °C to 325/350 °C and is intended for use in analytical gas chromatography workflows requiring low-polarity column chemistry.

Key Features:

• Column length: 50 m
• Inner diameter: 0.20 mm
• Film thickness: 0.33 µm
• Capillary tubing: Fused silica
• Phase: Ultra 2 (low polarity)
• Temperature range: -60 °C to 325/350 °C

Advantages:

• Low-polarity Ultra 2 phase enables general-purpose separations suitable for a wide range of volatile and semi-volatile compounds.
• Narrow 0.20 mm ID combined with 0.33 µm film thickness supports high-efficiency separations and good resolution for complex mixtures.
• Fused-silica capillary construction and a 50 m length provide extended column capacity and retention control for comprehensive GC and GC/MS analyses.
