• General purpose columns for solvent impurities, PCB congeners (e.g. Aroclor
mixes), simulated distillation, drugs of abuse, gases, natural gas odorants, sulfur
compounds, essential oils, hydrocarbons, semivolatiles, pesticides, oxygenates.
• Temperature range: -60 °C to 350 °C.
• Equivalent to USP G1, G2, G38 phases.
Rtx®-1 columns exhibit long lifetime and very low bleed at high operating tempera-
tures. A proprietary synthesis process eliminates residual catalysts that could cause
degradation and increase bleed.
