Rtx®-20Columns (fusedsilica)
(low tomidpolarityphase; Crossbond®20%diphenyl/80%dimethyl polysiloxane)
• General purpose columns for volatile compounds, flavor compounds,
alcoholic beverages.
• Temperature range: -20 °C to320 °C.
• Equivalent toUSPG28,G32phases.
Rtx®-20 polymer is synthesized to exacting standards. All residual catalysts and low
molecular weight fragments are removed from the polymer, providing a tight mono-
modal distribution and extremely lowbleed.
Rtx®-35Columns (fusedsilica)
(midpolarityphase; Crossbond®35%diphenyl/65%dimethyl polysiloxane)
• General purpose columns for organochlorine pesticides, PCB congeners (e.g.
Aroclormixes), herbicides, pharmaceuticals, sterols, rosin acids, phthalate esters.
• Temperature range: 40 °C to320 °C.
• Equivalent toUSPG42phase.
AnRtx®-35 column is apopular confirmation column for pesticides andherbicides, in
conjunctionwith an Rtx®-5 or Rtx®-1701 column. The higher phenyl content causes
useful elutionorder and retention time changes.
