Rxi®-XLB (Fused Silica)
Our new line of fused silica capillary GC columns - Rxi® columns - is now available! We have 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? Three things:
• Ultra-low bleed.
• Exceptional inertness.
• Reproducible performance, column after column.
- General purpose columns exhibiting extremely low bleed. Ideal for many GC/MS applications, including pesticides, PCB congeners or (e.g.) Aroclor mixes, PAHs.
- Unique selectivity.
- Temperature range: 30°C to 360°C.
Improvements in polymer synthesis and tubing deactivation enable us to make inert, stable Rxi®-XLB columns especially well-suited for analyzing active, high molecular weight compounds with sensitive GC/MS systems, including ion trap detectors. Excellent efficiency, coupled with inertness, low bleed, and high thermal stability, make Rxi®-XLB columns ideal for analyzing semivolatile compounds in drinking water (e.g., US EPA Method 525).
