Agilent CP-Wax 57 CB 50m x 0.32mm x 0.20um CP97753

The Agilent CP-Wax 57 CB (catalog CP97753) is a fused‑silica capillary GC column coated with the CP‑Wax 57 CB high‑polarity (PEG) phase. It is supplied as a 50 m column with a 0.32 mm inner diameter and a 0.20 µm film thickness and is intended for gas chromatographic separation of polar compounds. Manufacturer and authorized distributor descriptions highlight its use for analysis of alcohols, glycols and other polar volatile compounds (examples: brewing, wine/spirits, and related analyses) where good peak shape and selectivity are required.

Key Features:

• Column length: 50 m
• Inner diameter (ID): 0.32 mm
• Film thickness: 0.20 µm
• Phase: CP‑Wax 57 CB (polyethylene glycol, high polarity)
• Capillary tubing: fused silica
• Operating temperature range: approximately 60 °C to 200/225 °C

Advantages:

• High‑polarity CP‑Wax 57 CB phase provides unique selectivity for alcohols, glycols and other polar analytes, aiding reliable separation.
• High inertness (manufacturer/distributor described) yields improved peak shapes and precision for very polar compounds.
• 50 m × 0.32 mm × 0.20 µm geometry offers a balance of resolution and sample capacity suitable for routine quantitative analyses in food, beverage, and environmental labs.
