CP-Volamine Column

Agilent CP-Volamine GC Columns

Agilent J&W CP-Volamine GC columns are engineered specifically for the analysis of volatile amines, including monomethylamine (MMA), dimethylamine (DMA), and trimethylamine (TMA). These compounds are notoriously difficult to analyze due to their strong polarity, high reactivity, and tendency to adsorb to active sites within the chromatographic system.

CP-Volamine overcomes these challenges through a highly inert, nonpolar stationary phase combined with Agilent’s advanced Multi-Purpose Deactivation technology. This specialized deactivation minimizes analyte interaction with the column surface, enabling sharp, symmetrical peaks and consistent retention—critical for sensitive quantitation and reliable identification.

The column offers exceptional stability when analyzing samples with high water content, making it the most dependable solution for volatile amine applications in environmental, industrial, and chemical processing workflows. As an authorized distributor of Agilent GC columns, Chrom Tech provides full access to CP-Volamine formats that meet the demands of laboratories requiring accuracy, sensitivity, and long-term robustness.
Key Definitions â–¸
Multi-Purpose Deactivation (MPD)
Agilent’s advanced deactivation chemistry designed to eliminate active sites inside the column. MPD significantly improves peak shape and reproducibility for highly polar, reactive compounds such as volatile amines.
Volatile Amines (MMA, DMA, TMA)
Highly polar, low-boiling amine compounds—monomethylamine (MMA), dimethylamine (DMA), and trimethylamine (TMA)—commonly found in environmental, food processing, and chemical manufacturing settings. These compounds typically exhibit severe adsorption without specialized column deactivation.
Nonpolar Stationary Phase
A low-polarity GC stationary phase that provides controlled retention and reduced interaction for volatile amines. When paired with MPD, it supports sharp, symmetrical peaks even when samples contain a high percentage of water.
Frequently Asked Questions â–¸
Why are volatile amines difficult to analyze by GC?
Volatile amines are highly polar and reactive, causing them to adsorb to unpassivated surfaces inside the GC system. This results in poor peak shape, tailing, and inconsistent retention unless a column with specialized deactivation—such as CP-Volamine—is used.
What advantages does CP-Volamine offer over standard nonpolar GC columns?
CP-Volamine incorporates Agilent’s Multi-Purpose Deactivation technology, which eliminates active sites that interact with amines. This results in sharper, more symmetrical peaks and substantially improved reproducibility compared to standard nonpolar columns.
Can CP-Volamine handle samples with high water content?
Yes. CP-Volamine is exceptionally stable in the presence of high moisture levels, maintaining consistent retention and peak shape even when samples contain a significant percentage of water— a key advantage for real-world environmental and industrial amine analyses.
