Rtx®-200/Rtx®-200MS (fused silica)
• General-purpose columns for solvents, Freon® fluorocarbons, alcohols, ketones,
silanes, glycols, and drugs of abuse. Excellent confirmation column with an Rtx®-5
column for phenols, nitrosamines, organochlorine pesticides, chlorinated hydrocar-
bons, and chlorophenoxy herbicides.
• Temperature range: -20 °C to 340 °C.
• Equivalent to USP G6 phase.
Rtx®-200 columns have accomplished many difficult separations not possible on any
other bonded stationary phase. Many analysts consider these the best, most inert mid-
polarity columns available. The trifluoropropylmethyl polysiloxane stationary phase
has a unique selectivity that changes elution orders and resolves compounds that
phenyl, cyano, or Carbowax® phases can not. The Rtx®-200 column offers exceptional
thermal stability, low bleed, and superior inertness—even for active compounds such
as phenols, and with sensitive detectors such as ECDs, NPDs, and MSDs.
