A unique Crossbond® Carbowax® polyethylene glycol (PEG) stationary phase makes Rtx®-Wax columns 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.
