Agilent HP-50+, 30 meter, 0.25mm, 0.50 19091L-133

The Agilent HP-50+ 19091L-133 is a bonded, cross-linked fused‑silica capillary GC column (50% phenyl methylpolysiloxane phase) designed for gas chromatographic separations. With a 30 m length, 0.25 mm internal diameter and 0.50 µm film, it is intended for mid‑polarity analyses and is described by the manufacturer as suitable for confirmational analyses and routine GC separations. The column is solvent‑rinsable and manufactured to be compatible with USP G3 methods.

Key Features:

• Length: 30 m
• Inner diameter (ID): 0.25 mm
• Film thickness: 0.50 µm
• Phase: HP-50+ (50%‑phenyl methylpolysiloxane, mid polarity)
• Capillary tubing: fused silica
• Operating temperature range: 40 °C to ~280/300 °C
• Format: 7‑inch cage

Advantages:

• Mid‑polarity HP‑50+ phase (50% phenyl) provides improved selectivity for aromatic and moderately polar compounds, useful for confirmational analyses (manufacturer stated).
• Bonded, cross‑linked stationary phase is solvent‑rinsable, allowing column cleaning and extended service life.
• 0.25 mm ID with 0.50 µm film offers a balance of resolution and sample capacity for routine and confirmatory GC separations.
• Thermal stability to approximately 280/300 °C supports a wide range of GC temperature programs and analyte volatility.
