Agilent HP-5MS 30 Meter, 0.32mm, 0.25u 19091S-413

The Agilent J&W HP-5MS (19091S-413) is a 30 m fused‑silica capillary GC column with a low‑polarity HP-5ms phase (5% phenyl‑95% methylpolysiloxane) designed for gas chromatography–mass spectrometry (GC/MS). It is formulated for low column bleed and improved mass spectral integrity, making it suitable for routine volatile and semi‑volatile compound separations and analyses by GC/MS. Manufacturer and authorized distributor descriptions emphasize its suitability for sensitive GC/MS work and compatibility with common GC systems.

Key Features:

• Phase: HP-5ms (5% phenyl‑95% methylpolysiloxane)
• Length: 30 m
• Inner diameter (ID): 0.32 mm
• Film thickness: 0.25 µm
• Capillary tubing: fused silica
• Temperature range: −60 °C to 325/350 °C

Advantages:

• Low‑bleed formulation optimized for GC/MS yields improved signal‑to‑noise and cleaner mass spectra.
• Excellent inertness for active compounds (including acidic and basic analytes) improves peak shape and quantitation.
• Bonded, crosslinked, and solvent‑rinsable construction enhances column robustness and allows regeneration/cleaning.
• Wide operating temperature range supports a broad set of volatile and semi‑volatile GC applications.
