CP-Sil 8 CB Amines Column

Agilent CP-Sil 8 CB Amines GC Columns

Agilent J&W CP-Sil 8 CB for Amines is a specially engineered GC column designed to deliver optimized inertness and reliable performance for a broad range of amine compounds. Built on a base-deactivated 5% phenyl polydimethylsiloxane stationary phase, this column minimizes analyte interaction with active sites, significantly improving peak symmetry and retention stability for reactive amines.

With thermal stability up to 350 Â°C, CP-Sil 8 CB Amines provides robust, repeatable separations for C3–C20 amines, alkanol amines, and other challenging nitrogen-containing analytes. Its enhanced deactivation chemistry supports consistent, high-quality chromatographic performance across complex matrices, making it suitable for demanding industrial, petrochemical, and environmental applications.

As an authorized distributor of Agilent chromatography columns, Chrom Tech offers CP-Sil 8 CB Amines as a dependable and highly versatile solution for laboratories requiring durable, high-temperature operation and reproducible amine separations.
Key Definitions â–¸
Base-Deactivated Stationary Phase
A specially treated GC column surface that minimizes interaction between basic analytes (such as amines) and active sites inside the column. This reduces adsorption and tailing, resulting in sharper peaks and more consistent retention for reactive compounds.
5% Phenyl Polydimethylsiloxane
A mid-polarity GC stationary phase composed of 5% phenyl and 95% dimethylsiloxane. This blend provides balanced selectivity and strong thermal stability, enabling effective separation of C3–C20 amines and related nitrogen-containing compounds.
Alkanol Amines
Organic compounds containing both amine and alcohol functional groups. Their polarity makes them challenging to analyze by GC, but CP-Sil 8 CB Amines provides enhanced inertness and retention stability to ensure accurate profiling.
Frequently Asked Questions â–¸
What types of amines are best suited for CP-Sil 8 CB Amines columns?
CP-Sil 8 CB Amines is ideal for C3–C20 amines, alkanol amines, and a wide range of nitrogen-containing analytes. Its enhanced inertness and thermal stability support accurate, reproducible analysis across complex matrices.
How does the base-deactivated phase improve amine analysis?
Base deactivation prevents strong interactions between basic amines and active sites inside the GC column. This results in sharper peaks, reduced tailing, and improved retention consistency—crucial for reliable amine quantitation.
Can CP-Sil 8 CB Amines be used at high oven temperatures?
Yes. With thermal stability up to 350 Â°C, CP-Sil 8 CB Amines is well-suited for high-temperature methods requiring strong robustness and long column lifetime, even when analyzing reactive or high-boiling amines.
