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.
