13839 - Rxi-35Sil MS - Rxi-35Sil MS Columns (Fused Silica), Restek - Each

Rxi fused silica capillary GC columns are designed specifically for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. -Special selectivity and excellent inertness for substituted polar compounds, such as drugs, pesticides, herbicides, PCBs, phenols, etc. -Provides superior separation for cannabinoids -Very low-bleed phase for GC-MS analysis -Extended temperature range: 50C up to 360C -Reproducible performance, column after column -Mid-polarity Crossbond phase This combination of column characteristics assures Rxi columns will have long lifetimes 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. Restek has also developed a stable, reproducible manufacturing process, so that Rxi columns will meet your needs every time you install a new column.
