Restek Stabilwax-DB GC Columns

Restek Stabilwax-DB GC columns are engineered as low-bleed, high-inertness polyethylene glycol (PEG) columns specifically optimized for the analysis of flavor compounds, alcohols, fragrance components, and other polar analytes commonly found in foods, beverages, pharmaceuticals, and consumer products. The “DB” designation signifies *deactivated and bonded*, ensuring improved thermal stability and extended column lifetime compared to traditional nonbonded wax phases.

Stabilwax-DB delivers exceptional peak symmetry for alcohols, aldehydes, ketones, esters, organic acids, and other oxygenated volatiles. Its bonded PEG phase enables higher maximum operating temperatures and enhanced resistance to phase degradation—ideal for laboratories requiring long-term stability under routine high-throughput GC conditions.

These columns excel in applications such as alcoholic beverage profiling, flavor and fragrance composition studies, residual solvent analysis, fermentation monitoring, environmental VOC assessment, and food chemistry workflows. Their low bleed characteristics provide clean baselines suitable for GC-FID and GC-MS detection, ensuring robust performance for both qualitative and quantitative analyses of polar compounds.

Chrom Tech, as an authorized distributor of Restek columns, offers Stabilwax-DB in a wide range of dimensions for analytical laboratories needing reliable, bonded-PEG selectivity with elevated temperature stability and strong inertness for polar VOCs and semi-volatiles.
Key Definitions ▸
Bonded Polyethylene Glycol (PEG) Phase
A chemically bonded wax phase that offers greater thermal stability and solvent resistance than nonbonded PEG columns, extending lifetime and improving durability.
Polar Oxygenated Compounds
Volatile and semi-volatile species such as alcohols, aldehydes, ketones, and esters that require inert, wax-based phases for accurate chromatographic performance.
Low Phase Bleed
Reduced stationary-phase volatilization at elevated temperatures, resulting in cleaner baselines and better GC-MS sensitivity for trace-level analyses.
PEG Selectivity in Flavor/Fragrance Workflows
Wax phases offer excellent separation of alcohols, esters, and carbonyl-containing compounds—key analytes in aroma, taste, and sensory chemistry testing.
Deactivated Wax Column
A wax column treated to eliminate active sites, minimizing adsorption and peak tailing for highly polar and reactive analytes.
