Agilent HP-5MS Ultra Inert 30m, 0.25mm, 0.25um 19091S-433UI

The Agilent J&W HP-5MS Ultra Inert GC column (part number 19091S-433UI) is a 30 m fused‑silica capillary column with a 0.25 mm inner diameter and 0.25 µm film thickness, built on a (5%-phenyl)-methylpolysiloxane phase for low polarity separations. It is manufactured and tested for enhanced inertness and very low bleed to support GC/MS analysis of active, acidic and basic compounds and trace-level applications.

Key Features:

• Length: 30 m.
• Inner Diameter (ID): 0.25 mm.
• Film Thickness: 0.25 µm.
• Phase: HP-5ms Ultra Inert ((5%-phenyl)-methylpolysiloxane).
• Operating Temperature Range: -60 °C to 325/350 °C.

Advantages:

• Specifically tested for inertness with active, acidic and basic compounds, improving reliability for trace analyses.
• Very low bleed characteristics that preserve mass spectral integrity and reduce background in GC/MS.
• Improved signal-to-noise for better sensitivity in trace-level determinations and GC/MS workflows.
