Agilent CP-Wax 57 CB GC Columns

Agilent J&W CP-Wax 57 CB GC columns are engineered with a highly selective polyethylene glycol (PEG) phase that delivers exceptional performance for analyzing alcohols and other oxygenated volatile compounds. This selectivity makes CP-Wax 57 CB particularly effective for applications in the brewing, wine, and distilled spirits industries, where accurate quantitation of ethanol, higher alcohols, esters, aldehydes, and other flavor-impacting volatiles is essential for quality control and product characterization.

The column’s high inertness ensures sharp, symmetrical peak shapes for very polar analytes that often exhibit adsorption issues on less optimized phases. This inertness improves precision, stability, and reproducibility, enabling laboratories to achieve confident identification and quantitation of key aroma-active compounds in complex alcoholic beverages.

For laboratories requiring faster throughput, the 0.15 mm ID version offers a substantial gain in speed while preserving the resolution and selectivity needed for high-quality aroma and alcohol profiling. CP-Wax 57 CB provides the ideal balance of efficiency, selectivity, and robustness for beverage industry workflows and other applications involving polar oxygenated volatiles.

Key Definitions â–¸
CP-Wax 57 CB
A highly inert polyethylene glycol (PEG) GC column offering strong selectivity for alcohols and oxygenated volatiles. Commonly used in brewing, wine, and spirits analysis for profiling flavor and aroma compounds.
Polyethylene Glycol (PEG) Phase
A polar stationary phase used in GC to retain alcohols, aldehydes, esters, and other oxygenated compounds. PEG phases provide strong interactions with polar analytes, aiding in detailed separation of beverage volatiles and flavor compounds.
Oxygenated Volatiles
Volatile compounds containing oxygen—such as alcohols, esters, aldehydes, and organic acids—that contribute significantly to beverage aroma and flavor. CP-Wax 57 CB provides strong retention and resolution for these analytes.
0.15 mm ID Format
A narrow internal diameter column that enables faster separations and reduced analysis times while maintaining high selectivity and efficiency—ideal for high-throughput beverage profiling workflows.
Frequently Asked Questions â–¸
Why is CP-Wax 57 CB widely used in brewing and wine analysis?
CP-Wax 57 CB provides excellent retention and peak shape for alcohols and other oxygenated volatiles that drive aroma and flavor in beer, wine, and spirits. Its high inertness minimizes adsorption, ensuring accurate quantitation and reproducible results in beverage quality control.
What advantages does the 0.15 mm ID version offer?
The 0.15 mm ID format enables significantly faster analysis without sacrificing selectivity or resolution. This makes it ideal for high-throughput labs and rapid screening of beverage flavor compounds.
What types of compounds are best analyzed on CP-Wax 57 CB?
This highly selective PEG phase excels at analyzing alcohols, esters, aldehydes, organic acids, and other oxygenated volatiles common in beverages, essential oils, fermented products, and flavor/fragrance applications.
How does CP-Wax 57 CB maintain peak shape for very polar analytes?
The column’s high inertness minimizes active sites that typically cause tailing or adsorption of polar compounds. This results in sharp, symmetric peaks and improved precision for alcohols and other highly polar volatiles.
