Agilent HP-5MS Ultra Inert 20m, 0.18mm, 0.18um 19091S-577UI

The Agilent HP-5MS Ultra Inert 19091S-577UI is a 20 m, 0.18 mm ID, 0.18 µm film fused‑silica capillary GC/MS column supplied in a 7‑inch cage. It uses the HP-5ms Ultra Inert (5%-phenyl-methylpolysiloxane) phase specifically tested for inertness with active, acidic and basic compounds. The column is designed for low-bleed, high-sensitivity GC/MS analyses where mass spectral integrity and trace-level detection are required. It is intended for GC/MS applications requiring trace-level sensitivity and robust mass spectral data.

Key Features:

• Length: 20 m
• Inner diameter (ID): 0.18 mm
• Film thickness: 0.18 µm
• Phase: HP-5ms Ultra Inert (5%-phenyl-methylpolysiloxane)
• Format: 7-inch cage
• Capillary tubing: fused silica
• Temperature range: -60 °C to 325/350 °C

Advantages:

• Specifically tested for inertness with active (acidic and basic) compounds, improving recovery and peak shape for reactive analytes.
• Very low-bleed characteristics optimized for GC/MS to improve signal-to-noise and preserve mass spectral integrity.
• Bonded, crosslinked and solvent-rinsable construction supports cleaning and extends column lifetime.
• Equivalent to USP phase G27, aiding method comparability and transfer between systems.
