GENERAL-PURPOSE COLUMNS

Stabilwax®-MS

Stabilwax®-MS Columns

(fused silica)

• 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.

• Temperature range: 40 °C to 250/260 °C.

• Equivalent to USP G14, G15, G16, G20, and G39 phases.

New Stabilwax®-MS columns ensure reproducible retention times from run to run,

even with temperature cycling. When methods require trace analysis, this highly

polar, low-bleed stationary phase produces excellent signal-to-noise levels! Ideal for

food and flavor analysis (e.g., essential oils), fragrance and allergen analysis, as well as

industrial solvent and chemical analysis.
