Rtx-2330
Restek Rtx-2330 GC Columns
Restek Rtx-2330 GC columns are highly polar cyanopropyl-containing phases specifically engineered for the
detailed resolution of structural, geometric, and positional isomers—particularly fatty acid methyl esters
(FAMEs). The stationary phase features a 90% biscyanopropyl, 10% cyanopropylphenyl polysiloxane chemistry,
making Rtx-2330 one of the most polar GC phases in the Restek portfolio. This level of polarity enables
unmatched selectivity for complex mixtures where analytes share similar boiling points but differ in subtle
structural features.
Rtx-2330 excels at resolving cis/trans FAME isomers, short- through long-chain FAMEs, and challenging positional variants that require extremely high separation efficiency. Its superior isomer resolution is widely used in food and nutritional research, biodiesel characterization, lipid profiling, forensic investigations, and other analytical workflows involving fatty acids or structurally complex polar analytes.
The column’s strong polar functionality enhances dipole and hydrogen-bonding interactions, providing highly structured elution patterns and stable retention behavior. With robust deactivation chemistry, low bleed, and excellent thermal stability for such a polar phase, Rtx-2330 supports both GC and GC-MS workflows requiring precise, reproducible separation of intricate isomeric mixtures.
As an authorized Restek distributor, Chrom Tech supplies Rtx-2330 columns in a variety of lengths, IDs, and film thicknesses—ensuring laboratories can achieve the highest resolution possible for fatty acid and isomer-specific analyses.
