Agilent HP-50+, 30 meter, 0.25mm, 0.25 19091L-433

The Agilent 19091L-433 is a J&W/Agilent HP-50+ fused‑silica capillary GC column (30 m length) with a 0.25 mm inner diameter and 0.25 µm film thickness, intended for gas chromatography and GC/MS separations. The stationary phase is 50% phenyl‑methylpolysiloxane (HP‑50+), a mid‑polarity phase recommended for confirmational analyses of polar analytes such as chlorinated pesticides, herbicides, and basic drugs. The column is specified with an approximate operating range of 40 °C to 280/300 °C.

Key Features:

• Phase: HP-50+ (50% phenyl‑methylpolysiloxane).
• Length: 30 m.
• Inner Diameter (ID): 0.25 mm.
• Film thickness: 0.25 µm.
• Temperature range: ~40 °C to 280/300 °C.

Advantages:

• Mid‑polarity HP‑50+ phase provides complementary selectivity for confirmational analyses of polar and semi‑polar compounds (e.g., chlorinated pesticides, herbicides, basic drugs).
• 30 m length with 0.25 mm ID and 0.25 µm film offers a balance of separation efficiency and practical analysis time for GC and GC/MS methods.
• Bonded, cross‑linked stationary phase and vendor QC/testing improve column stability and reproducibility for qualitative and quantitative analyses.
