Agilent HP-1MS 15m, 0.25mm, 0.25u 19091S-931

The Agilent HP-1MS (part number 19091S-931) is a 15 m fused‑silica capillary gas chromatography column with a 0.25 mm inner diameter and 0.25 µm film thickness, specified by Agilent for GC/MS use. It uses the nonpolar HP-1ms phase (low polarity) and is rated over a wide operating range (−60 °C to 325/350 °C). Typical applications are routine GC/MS separations of volatile and semi‑volatile compounds in analytical and research laboratories.

Key Features:

• Length: 15 m
• Inner diameter (ID): 0.25 mm
• Film thickness: 0.25 µm
• Phase: HP-1ms (low polarity)
• Capillary tubing: fused silica
• Operating temperature range: -60 °C to 325/350 °C

Advantages:

• Designed explicitly for GC/MS, ensuring compatibility with mass‑spectrometric detection.
• 15 m length with 0.25 mm ID and 0.25 µm film offers a balance of resolution and sample throughput.
• Wide temperature rating up to 325/350 °C supports analysis of volatile through higher‑boiling analytes.
• Fused‑silica capillary construction provides a chemically inert support for reliable separations.
