Stabilwax^® GC-Column:

Rugged enough to withstand repeated water injections
Low-bleed PEG column ensures long column lifetimes
Applications: FAME, flavor, essential oils, solvents, aromatic compounds (incl. Xylol Isomers), acrolein/acrylnitrile, oxygen containing compounds, purity determination of water and alcoholic beverages

Stabilwax-DA GC-Column:

Resistant to oxidative damage
Application-specific columns for free (underivatized) acids, some inorganic acids.
Ideal for analyzing distilled liquor and other alcoholic beverages.

Stabilwax-DB GC-Column:

No need for column priming
Stabilwax^®-DB Columns should not be flushed with water or alcohol
Application-specific columns for underivatized amines and other basic compounds, including alkylamines, diamines, triamines, nitrogen-containing heterocyclics

Stabilwax-MS GC-Column:

High-polarity, stable polyethylene glycol (PEG) stationary phase
Low bleed and rugged enough to withstand repeated temperature cycles without retention time shifting
Ideal for food, flavor, fragrance, and industrial chemical and solvent analysis.
