Restek Rxi-1ms GC Columns | Ultra-Low Bleed GC-MS Columns

Rxi-1ms GC Columns

CrossBond
Dimethyl Polysiloxane

Rxi-1ms combines ultra-low bleed, exceptional inertness, and outstanding reproducibility to meet the demands of modern GC/MS laboratories. Individually performance tested and manufactured with Restek's advanced deactivation technology, it delivers reliable peak shapes, excellent mass spectral integrity, and consistent analytical performance across an exceptionally broad range of routine and trace-level applications.

Ultra-low bleed minimizes background noise, improving signal-to-noise ratio, detector cleanliness, and mass spectral integrity for high-sensitivity GC/MS analyses.
Exceptional inertness provides sharp, symmetrical peaks for active and challenging compounds while reducing adsorption and improving quantitative accuracy.
Individually tested for bleed, efficiency, inertness, and stationary phase performance to ensure excellent column-to-column reproducibility and dependable analytical results.
Designed for a wide range of applications including hydrocarbons, pesticides, PCB congeners (Aroclor mixtures), sulfur compounds, amines, oxygenates, solvent impurities, gasoline range organics (GRO), refinery gases, simulated distillation, arson accelerants, and essential oils.
Optimized for modern GC/MS systems requiring high sensitivity, low background, and consistent long-term performance.
Equivalent to USP G1, G2, and G38 phases.
