*Maximum temperatures listed are for shorter length columns. Longer columns may have a different maximum temperature.

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.
