Agilent CP-Sil 5 CB 50m x 0.32mm x 5.0um CP7690

The Agilent CP-Sil 5 CB CP7690 is a fused‑silica capillary gas chromatography (GC) column coated with the CP‑Sil 5 CB low‑polarity stationary phase, provided as 50 m x 0.32 mm with a 5.0 µm film. It is intended for analytical GC separations where a long column length and thick film improve capacity and retention for less-volatile or higher-load samples. The column is supplied in the standard 7‑inch cage format and is rated for operation from −60 °C up to ≈300/325 °C.

Key Features:

• Length: 50 m.
• Inner diameter: 0.32 mm.
• Film thickness: 5.0 µm.
• Phase: CP‑Sil 5 CB (low polarity).
• Capillary tubing: Fused silica.
• Temperature range: −60 °C to 300/325 °C.
• Format: 7‑inch cage (standard GC column format).

Advantages:

• Thick 5.0 µm film increases sample capacity and improves retention of less-volatile or higher-load analytes (inference from confirmed film thickness).
• Low‑polarity CP‑Sil 5 CB phase offers suitable selectivity for nonpolar/low‑polarity separations, supporting a broad range of GC analyses.
• Wide certified temperature range (down to −60 °C and up to ~300/325 °C) enables analysis of compounds across varied volatilities and thermal stabilities.
• Standard 7‑inch fused‑silica format ensures straightforward installation and compatibility with common GC instrument ovens.
