Rtx®-20 polymer is synthesized to exacting standards so that all residual catalysts and low molecular weight fragments are removed from the polymer, providing a tight mono-modal distribution and extremely low bleed.

• General-purpose columns for volatile compounds, flavor compounds, alcoholic beverages
• Temperature range: −20 to 320 °C
• Equivalent to USP G28, G32 phases
• Low- to mid-polarity phase; Crossbond® diphenyl dimethyl polysiloxane

Rtx®-20 columns are made of fused silica and feature extremely low bleed levels.
