Agilent CP-Sil 5 CB 50m x 0.25mm x 0.12um CP7720

The Agilent CP-Sil 5 CB (CP7720) is a 50 m fused‑silica capillary GC column coated with a CP‑Sil 5 CB (100% dimethylpolysiloxane) low‑polarity phase. It is built for general‑purpose gas chromatographic separations where separation is driven primarily by boiling point/volatility, and is offered in a 0.25 mm ID with a 0.12 µm film thickness. Typical use cases include analysis of hydrocarbons, solvents, flavors, and pharmaceutical-related compounds across a broad temperature range (−60 °C to 330/350 °C).

Key Features:

• Length: 50 m
• Inner Diameter (ID): 0.25 mm
• Film Thickness: 0.12 µm
• Phase: CP-Sil 5 CB (100% dimethylpolysiloxane)
• Temperature Range: −60 °C to 330/350 °C
• Format: 7-inch capillary column (7" cage)

Advantages:

• Low‑polarity 100% dimethylpolysiloxane phase gives broad, boiling‑point based separations suitable for many volatile and semi‑volatile analytes.
• Bonded and cross‑linked phase delivers high inertness, reducing sample adsorption and improving peak shape and reproducibility.
• Low‑bleed construction and QC testing improve sensitivity and stability at elevated temperatures, aiding MS and FID applications.
• Wide operating temperature range supports analyses that require high‑temperature elution of less volatile compounds.
