Restek Rtx-5 Amine GC Columns

Restek Rtx-5 Amine GC columns are specially engineered low-polarity columns designed to overcome one of the most persistent challenges in amine chromatography: adsorption, peak tailing, and poor recovery caused by active sites within standard GC columns. Built on the familiar 5% phenyl, 95% dimethylpolysiloxane stationary phase, Rtx-5 Amine retains the broad applicability and thermal stability of the traditional Rtx-5 design while incorporating a proprietary amine-inert deactivation that dramatically improves performance with nitrogen-containing analytes.

Rtx-5 Amine columns deliver exceptional peak symmetry and sensitivity for primary, secondary, and tertiary amines, including volatile aliphatic amines, aromatic amines, heterocyclic amines, amides, and other reactive nitrogenous compounds. This makes the column ideal for environmental testing, petrochemical analysis, industrial hygiene monitoring, flavor and fragrance profiling, agricultural chemical testing, and the quantitation of amines in complex matrices.

With low bleed, strong inertness, and outstanding reproducibility, Rtx-5 Amine supports both GC and GC-MS workflows requiring reliable quantitation and sharp peak shapes across a wide range of amine classes. Analysts gain the benefits of a rugged, low-polarity column—high temperature limits, compatibility with diverse analytes, and fast elution—combined with the specialized surface treatment needed for high-performance amine chromatography.

As an authorized Restek distributor, Chrom Tech supplies Rtx-5 Amine columns in multiple dimensions to support trace-level amine analysis, method development, and routine industrial workflows that demand maximum inertness and consistent performance.
Key Definitions ▸
Amine-Inert Deactivation
A proprietary Restek deactivation process designed to minimize adsorption and tailing of amines by eliminating active sites that react with or retain nitrogen-containing compounds.
5% Phenyl Polysiloxane Phase
A low-polarity stationary phase used widely for general-purpose GC applications. Rtx-5 Amine combines this familiar selectivity with enhanced inertness for nitrogen-containing compounds.
Amine Class Selectivity
Rtx-5 Amine provides strong inertness and consistent retention behavior for aliphatic, aromatic, heterocyclic, and multifunctional amines, enabling high-quality separations across all amine classes.
Low-Polarity Selectivity
The underlying 5% phenyl phase delivers fast elution, high thermal stability, and broad compatibility, while the amine-optimized surface ensures accurate quantitation for reactive compounds.
Rtx® Deactivation
Advanced deactivation technology that minimizes activity inside the column, ensuring sharper peaks and improved repeatability for amine and amide analytes.
Frequently Asked Questions ▸
What is the main advantage of using an Rtx-5 Amine column?
Its specialized amine-inert deactivation dramatically reduces adsorption and improves peak symmetry for nitrogen-containing compounds that typically tail or degrade on standard GC phases.
Can Rtx-5 Amine be used for GC-MS workflows?
Yes. Its low-bleed characteristics and high inertness support sensitive GC-MS analysis of a wide range of amines at trace concentrations.
Which industries commonly use Rtx-5 Amine columns?
Environmental labs, petrochemical facilities, chemical manufacturers, industrial hygiene programs, pharma/biotech R&D, and fragrance/flavor chemists routinely rely on Rtx-5 Amine for analyzing reactive and volatile amines.
When should I select Rtx-5 Amine instead of Rtx-35 Amine?
Choose Rtx-5 Amine when you need a lower-polarity column with faster elution, higher temperature limits, and broader general-purpose compatibility—while still retaining amine-inert performance for reactive nitrogenous compounds.
