Rxi®-5Sil MS stationary phase incorporates phenyl groups in the polymer backbone. This improves thermal stability, reduces bleed, and makes the phase less prone to oxidation. These columns are ideal for GC-MS applications requiring high sensitivity, including use in ion trap systems.

• Low-bleed GC-MS column
• Low polarity phase; Crossbond 1,4-bis(dimethylsiloxy)phenylene dimethyl polysiloxane columns
• Temperature range: −60 to 350 °C

Ideal for semivolatiles, polycyclic aromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines, organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities, and hydrocarbons.
