        Rtx-Wax

        (Crossbond® Carbowax® polyethylene glycol)GC column

        • Polar phase.
        • Equivalent to USP G14, G15, G16, G20, and G39 phases.

        Rtx®-Wax columns are the most inert and efficient PEG columns currently available. The extended operating temperature range allows analysis of compounds having a wide volatility range, and ensures low bleed at temperatures as high as 250°C. Selectivity is comparable to other Carbowax® columns, for compounds of intermediate to high polarity. Selectivity data available on request.
