Agilent HP-5MS Ultra Inert 30m, 0.25mm, 0.50um 19091S-133UI

The Agilent J&W HP-5ms Ultra Inert 19091S-133UI is a 30 m × 0.25 mm × 0.50 µm fused‑silica GC capillary column (7‑inch format) designed for gas chromatography and GC–MS applications. The HP-5ms Ultra Inert phase (low polarity) is optimized for trace‑level analysis and for active compounds, including acidic and basic analytes, while supporting a wide temperature range (−60 °C to 325/350 °C). The column is compatible with Agilent 5890/6890/7820/7890/8860/8890 series systems and other ovens of similar size.

Key Features:

• Part number: 19091S-133UI
• Length: 30 m
• Inner Diameter (ID): 0.25 mm
• Film Thickness: 0.50 µm
• Phase: HP-5ms Ultra Inert (low polarity)
• Temperature range: −60 °C to 325/350 °C
• Format: 7 inch (standard GC column cage)

Advantages:

• Ultra Inert surface engineered and tested for active compounds (including acids and bases), enabling more accurate trace‑level analyses.
• Very low column bleed suitable for GC–MS, improving sensitivity and reducing background noise.
• Improved signal‑to‑noise and mass spectral integrity for better detection and identification by MS.
• Bonded, crosslinked, fused‑silica construction and solvent‑rinsable design for robustness and extended column life.
