The NEW Restek line of fused silica
capillary GC columns - Rxi™ columns - is now available! - Restek have designed these new 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.
- 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?
Three things:
- 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)
- Restek Columns have always been at the forefront of tecnology
These Rxi Columns surpass all others on the market in low inertness and low bleed
