Rxi®-5Sil MS Columns
(fused silica)
(low polarity Crossbond® silarylene phase; selectivity close to 5% phenyl/95% dimethyl
arylene polysiloxane)
• Engineered to be a low bleed GC/MS column.
• Excellent inertness for active compounds.
• General purpose columns—ideal for GC/MS analysis of polycyclic aromatic
compounds, chlorinated hydrocarbons, phthalates, phenols, amines,
organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities,
and hydrocarbons.
• Temperature range: -60 °C to 350 °C.
