Rtx®-20 columns are general purpose columns for volatile compounds, flavour compounds, alcoholic beverages.

• Low to midpolarity phase; Crossbond® diphenyl dimethyl polysiloxane
• Temperature stability up to 320 °C
• Equivalent to USP G28, G32 phases

Rtx®-20 polymer is synthesised to exacting standards. All residual catalysts and low molecular weight fragments are removed from the polymer, providing a tight monomodal distribution and low bleed.
