[1] Abhängig von der Schichtdicke und davon, ob man bei konstanter Temperatur oder mit einem Gradienten arbeitet [2] Für Schicht = 2,0 µm [3] Für Schicht = 1,5 µm [4] Für Schicht = 1,0 µm [5] Für Schicht < 1,0 µm
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.
