*Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced
maximum temperature.
(fused silica)
(polar phase; Crossbond® Carbowax® polyethylene glycol)
• Best polyethylene glycol (PEG) phase for alkenols, glycols, and aldehydes.
• Temperature range: 20 °C to 250 °C.
• Equivalent to USP G14, G15, G16, G20, 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 wid
volatility range, and ensures low bleed at temperatures as high as 250 °C. Selectivity i
comparable to other Carbowax® columns, for compounds of intermediate to hig
polarity. Selectivity data available on request.
