Midpolarity phase; similar to 35% phenyl/65% dimethyl polysiloxane. Special selectivity and excellent inertness for substituted polar compounds, such as drugs, pesticides, herbicides, PCBs, phenols, etc. Very low bleed phase for GC/MS analysis. Extended temperature range: 50 °C to 340/360 °C.
What do Rxi® columns mean to you? Three things:
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 needs every time you install a new column.
