Rxi-5HT Columns (fused silica)

low-polarity phase; diphenyl dimethyl polysiloxane

Rxi fused silica capillary GC columns were designed 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

• 40% longer lifetime from specially designed fused silica tubing.
• Columns processed for high-temperature applications, such as mineral oil.
• Temperature range: -60 to 400°C
