Rxi Brochure 24p DJVuSpecial Offer ( to Oct 31,07  )

Restek's new line of fused silica capillary GC columns - Rxi™ columns
- are now available! . . . 2006
Equivalent to other "-1" and "-5" Phase columns re selectivity & retention times
but with superior inertness and low bleed

UPDATE  . . .  NEW 2007 Rxi-17 and Rxi-50 released July 2007 Enquire !
NEW Rxi Columns Overview ( PDF : DJVu )
Chromatograms; semi-Volatiles, drugs, acidic/neutral AND mild basic compounds; underivatised drugs all at low/sub ng levels (on-column) and with perfect peak shapes

Restek have designed these new Rxi columns specifically to be the best columns available,
for low bleed, exceptional inertness, and reproducible retention and selectivity.
In addition to outstanding performance, this combination of column characteristics assures Rxi™ columns will have long lifetimes.
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 . . . or are looking for a superior replacement for one of your existing or competitors columns
Main features of Rxi™ columns
  • Low bleed.
  • Exceptional inertness.
  • Reproducible performance, column after column.

  • General purpose columns for semivolatiles, phenols, amines, residual solvents, drugs of abuse, pesticides, PCB congeners or (e.g.) Aroclor® mixes, solvent impurities.
  • Temperature range: -60°C to 330/350°C (bleed tested temperature/maximum operating temperature).
  • Low bleed - improved signal to noise ratio, for better sensitivity and mass spectral integrity.
  • Equivalent to USP G27 phase.
    (Crossbond® 5% diphenyl / 95% dimethyl polysiloxane)

  • 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.
    • Temperature range: -60°C to 330/350°C (bleed tested temperature/maximum operating temperature).
    • Ultra-low bleed - improved signal to noise ratio, for better sensitivity and mass spectral integrity.
    • Equivalent to USP G2 phase.
