Rxi® fused silica capillary GC columns are designed specifically for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity.

• Convenient 2 m length is ideal for use as a secondary column in GCxGC analyses
• 340/360 °C upper temperature limits
• Excellent inertness and selectivity for active environmental compounds, such as PAHs
• Low-bleed for use with sensitive detectors, such as MS
• Reproducible performance, column after column
• Mid-polarity Crossbond® phase

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.
