Restek Stabilwax-MS GC Columns

Restek Stabilwax-MS GC columns are ultra-low-bleed, high-polarity polyethylene glycol (PEG) columns engineered specifically for GC-MS applications requiring exceptional sensitivity, strong inertness, and superior separation of oxygenated compounds. As the MS-grade version of Restek’s Stabilwax line, Stabilwax-MS combines the advantages of a bonded/crosslinked PEG phase with a highly optimized deactivation process to deliver the cleanest possible baselines for mass spectrometric detection.

Featuring Restek’s proprietary deactivation and ultra-low-bleed PEG chemistry, Stabilwax-MS produces sharper peaks, reduced adsorption, and extremely low stationary-phase bleed—even during extended high-temperature operation. This makes it ideal for analyzing alcohols, aldehydes, ketones, esters, organic acids, glycols, flavor and fragrance volatiles, and other polar compounds where MS sensitivity and chromatographic integrity are critical.

Stabilwax-MS columns offer excellent lot-to-lot reproducibility, solvent-rinseability, and long-term thermal stability, making them highly reliable for validated methods, complex sample matrices, and high-throughput workflows in food, environmental, petrochemical, and industrial testing laboratories.

As an authorized distributor of Restek products, Chrom Tech supplies Stabilwax-MS columns in a full selection of formats to support laboratories needing a robust, MS-optimized PEG column for the most challenging polar compound separations.
Key Definitions ▸
MS-Grade PEG Column
A polyethylene glycol stationary phase engineered with ultra-low bleed characteristics suitable for high-sensitivity mass spectrometric detection.
Ultra-Low Bleed
Significantly reduced stationary-phase off-gassing, resulting in cleaner mass spectra, improved detection limits, and superior baseline stability during high-temperature operation.
Bonded & Crosslinked PEG Phase
A chemically bonded and reinforced polyethylene glycol phase that supports solvent rinsing and extended thermal durability without degradation.
Polar Compound Inertness
Specialized deactivation prevents adsorption of reactive polar analytes, ensuring reproducible retention behavior and peak shape.
GC-MS Optimization
Column characteristics designed specifically to enhance mass spectrometric response, spectral clarity, and long-term system cleanliness.
Frequently Asked Questions ▸
What applications are Stabilwax-MS columns best suited for?
Stabilwax-MS is ideal for GC-MS analysis of alcohols, aldehydes, ketones, esters, carboxylic acids, glycols, and flavor and fragrance compounds requiring the lowest possible bleed.
How does Stabilwax-MS differ from Stabilwax?
Stabilwax-MS undergoes an advanced deactivation and ultra-low-bleed formulation designed for high-sensitivity MS detection, whereas Stabilwax is optimized primarily for GC-FID workflows.
Can Stabilwax-MS be solvent-rinsed?
Yes. Its bonded and crosslinked chemistry allows solvent rinsing to remove matrix buildup and extend column lifetime without damaging the stationary phase.
Is Stabilwax-MS suitable for long temperature programs?
Absolutely. Stabilwax-MS is engineered to maintain low bleed and high stability even during extended high-temperature operation, typical of complex polar compound separations.
