Rxi®-5Sil MS Columns (fused silica)
(low-polarity phase; Crossbond® 1,4-bis(dimethylsiloxy)phenylene dimethyl polysiloxane)
• Engineered to be a low-bleed GC-MS column.
• Excellent inertness for active compounds.
• General-purpose columns—ideal for GC-MS analysis of semivolatiles, polycyclic
aromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines,
organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities,
and hydrocarbons.
• Temperature range: -60 °C to 350 °C.
The Rxi®-5Sil MS stationary phase incorporates phenyl groups in the polymer back-
bone. This improves thermal stability, reduces bleed, and makes the phase less prone
to oxidation. Rxi®-5Sil MS columns are ideal for GC-MS applications requiring high
sensitivity, including use in ion trap systems.
