Agilent CP-Sil 24 CB 30m x 0.25mm x 0.50um CP7824

The Agilent CP-Sil 24 CB (CP7824) is a fused‑silica GC capillary column (30 m × 0.25 mm × 0.50 µm) with a mid‑polarity 50% phenyl/50% dimethylpolysiloxane phase designed for gas chromatographic separations. It is intended for applications requiring mid‑polarity selectivity — commonly used for analysis and confirmation of drugs and pesticides — and is reported to give sharp peaks for amines and be suitable for electron capture detection (ECD).

Key Features:

• Length: 30 m.
• Inner diameter: 0.25 mm.
• Film thickness: 0.50 µm.
• Phase: CP‑Sil 24 CB (50% phenyl / 50% dimethylpolysiloxane).
• Operating temperature range: ~40 °C to 280/300 °C.

Advantages:

• Mid‑polarity 50% phenyl phase improves selectivity for aromatic and polar analytes, aiding drugs and pesticide separations.
• Produces sharp, well‑shaped peaks for amines (Grob test), supporting better quantitation of basic analytes.
• Low column bleed characteristics support sensitive ECD and trace‑level detection.
• Offered in common GC formats (30 m, 7‑inch cage) for straightforward installation and method confirmation workflows.
