Agilent CP-Sil 24 CB-MS 30m x 0.32mm x 0.25um CP5826

The Agilent J&W CP-Sil 24 CB-MS (CP5826) is an MS-grade fused‑silica capillary GC column specified as 30 m × 0.32 mm × 0.25 µm. It employs a mid‑polarity 50% phenyl / 50% dimethylpolysiloxane stationary phase and is intended for gas chromatography, including mass‑spectrometry and ECD confirmation work. Typical applications called out by the manufacturer include separation of amines, drugs and pesticides; the MS/low‑bleed construction supports trace analysis and stable detector performance.

Key Features:

• Length: 30 m.
• Inner diameter (ID): 0.32 mm.
• Film thickness: 0.25 µm.
• Stationary phase: 50% phenyl / 50% dimethylpolysiloxane (mid polarity).
• Format / mounting: J&W CP‑Sil 24 CB‑MS, fused silica, 7 in. cage.
• Temperature range: commonly listed ~40 to 280/300 °C for this phase.

Advantages:

• MS‑grade / low‑bleed construction improves sensitivity and reduces detector contamination during GC‑MS runs.
• Mid‑polarity 50% phenyl phase provides good selectivity for amines, drugs and pesticide analyses.
• Bonded and cross‑linked polymer offers solvent rinsability and extended column lifetime.
• Supplied in an EZ‑GRIP 7‑inch cage to simplify installation, coupling and handling.
