Rtx®-WaxColumns
(fusedsilica)
(polar phase; Crossbond®Carbowax®polyethyleneglycol)
• Best polyethylene glycol (PEG) phase for alkenols, glycols, and aldehydes.
• Temperature range: 20 °C to250 °C.
• Equivalent toUSPG14,G15,G16,G20,G39phases.
Rtx®-Wax columns are themost inert and efficient PEG columns currently available.
Theextendedoperating temperature rangeallowsanalysisof compoundshavingawide
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. Selectivitydata available on request.
