What do Rxi columns mean to you? Three things:

Ultra-low bleed.
Exceptional inertness.
Reproducible performance, column after column.

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. Restek chemists have also developed a stable, reproducible manufacturing process so that Rxi columns will meet your needs every time you install a new column.

The higher aromatic content of the Rxi-35Sil MS column allows for superior separation of cannabinoids over traditional 5-type columns. Baseline separation can be achieved for a comprehensive list of cannabinoids by using a cost-effective 15 m column and readily available hydrogen carrier gas. The arylene content of the Rxi-35Sil MS stationary phase ensures long column lifetime at the high elution temperatures required for cannabinoids analysis.
