Turning Visions Into Reality Restek Corporation is one of the world’s leading manufacturers of high-quality chromatography products. As innovators of GC, HPLC, Air Monitoring and Gas Sampling products, Restek focuses on "Plus 1" service and quality products.
Introducing Restek's Rxi™ Capillary GC Columns... Our new line of fused silica capillary GC columns - Rxi™ columns - is now available! Restek has designed these new columns specifically to be the best columns available for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to outstanding performance, this combination of column characteristics assures Rxi™ columns will have long lifetimes. The Restek chemists also have developed a stable, reproducible manufacturing process, so that Rxi™ columns will meet your needs every time you install a new column. What do Rxi™ columns mean to you?
Reproducible performance, column after column.
General purpose columns for drugs of abuse, essential oils, hydrocarbons, pesticides, PCB congeners or (e.g.) Aroclor® mixes, sulfur compounds, amines, solvent impurities, simulated distillation, oxygenates, gasoline range organics (GRO), refinery gases.
Ultra-low bleed - improved signal to noise ratio, for better sensitivity and mass spectral integrity.
Temperature range: -60°C to 330/350°C (bleed tested temperature/maximum operating temperature).
Equivalent to USP G2 phase. (Crossbond® 100% dimethyl polysiloxane)
