Rtx®-1 Columns
(fused silica)
(nonpolar phase; Crossbond® dimethyl polysiloxane)
• General-purpose columns for solvent impurities, PCB congeners (e.g., Aroclor
mixes), simulated distillation, arson accelerants, gases, natural gas odorants, sulfur
compounds, essential oils, hydrocarbons, semivolatiles, pesticides, oxygenates.
• Long lifetime and very low bleed at high operating temperatures.
• Temperature range: -60 °C to 350 °C.
• Equivalent to USP G1, G2, G38 phases.
