HIGH-PERFORMANCE Rxi® COLUMNS
Rxi®-1ms
Rxi®-1ms Columns
(fused silica)
(nonpolar phase; Crossbond® dimethyl polysiloxane)
• General-purpose columns for arson accelerants, essential oils, hydrocarbons,
pesticides, PCB congeners (e.g., Aroclor mixes), sulfur compounds, amines,
solvent impurities, simulated distillation, oxygenates, gasoline range organics
(GRO), refinery gases.
• Tested and guaranteed for ultra-low bleed; improved signal-to-noise ratio for
better sensitivity and mass spectral integrity.
• Temperature range: -60 °C to 330/350 °C.
• Equivalent to USP G1, G2, and G38 phases.
