Restek Rtx-Biodiesel TG GC Columns

Restek Rtx-Biodiesel TG GC columns are engineered specifically for high-resolution triglyceride (TG) and biodiesel component analysis, providing the selectivity needed to characterize feedstocks, monitor production quality, and ensure compliance with biodiesel specifications. Featuring a highly polar stationary phase designed to resolve complex lipid mixtures, Rtx-Biodiesel TG delivers outstanding separation of mono-, di-, and triglycerides, free fatty acids, sterol contaminants, and other biodiesel-related compounds.

These columns excel in fatty acid methyl ester (FAME) profiling, triglyceride distribution analysis, and monitoring biodiesel conversion efficiency. The phase’s strong aromatic and dipole-interaction capability provides enhanced resolution for saturated and unsaturated species, cis/trans isomers, and long-chain lipid structures that often overlap on conventional GC phases.

Rtx-Biodiesel TG columns are optimized for the high-temperature chromatography required to elute heavy lipid species while maintaining low bleed and stable baseline performance. Restek’s advanced deactivation ensures excellent peak shapes for both polar and nonpolar biodiesel components, enabling accurate quantitation and reproducible results in GC-FID and GC-MS workflows.

Chrom Tech, as an authorized distributor of Restek products, offers Rtx-Biodiesel TG columns in multiple dimensions tailored for biodiesel laboratories, edible-oil producers, renewable fuel R&D programs, and regulatory environments requiring detailed triglyceride and FAME characterization.
Key Definitions ▸
Triglyceride Profiling
The examination of mono-, di-, and triglyceride composition to monitor biodiesel conversion efficiency and ensure feedstock quality.
Fatty Acid Methyl Esters (FAME) Analysis
A core application in biodiesel testing where fatty acids are derivatized to FAMEs for GC analysis; Rtx-Biodiesel TG columns deliver strong isomer and chain-length resolution.
High-Temperature Lipid Chromatography
The high oven temperatures required to elute long-chain triglycerides. Rtx-Biodiesel TG is engineered to withstand these conditions while maintaining low bleed.
Lipid Isomer Resolution
The ability to separate cis/trans and positional isomers commonly found in biodiesel feedstocks and edible oils—where structural differences affect fuel quality.
Mixed Analyte Inertness
Engineered inertness allows Rtx-Biodiesel TG to provide stable peak shapes across both polar and nonpolar biodiesel components—from free fatty acids to long-chain triglycerides.
Frequently Asked Questions ▸
What applications are Rtx-Biodiesel TG columns designed for?
These columns are optimized for biodiesel quality control, triglyceride distribution analysis, FAME profiling, feedstock characterization, and related renewable fuel workflows.
How does Rtx-Biodiesel TG differ from Rtx-65TG?
Rtx-Biodiesel TG is specifically tuned for biodiesel and triglyceride profiling workflows, whereas Rtx-65TG is targeted more broadly toward high-polarity lipid separations including both triglycerides and FAMEs.
Can these columns be used with GC-MS?
Yes. Rtx-Biodiesel TG provides low bleed and strong thermal stability, supporting sensitive GC-MS detection of biodiesel contaminants and lipid species.
Are these columns compatible with high-temperature programs needed for triglyceride elution?
Absolutely. Rtx-Biodiesel TG is engineered for the extended high-temperature conditions required to elute long-chain triglycerides while maintaining stable baseline and low bleed.
