Metal MXT® Columns
Rugged, flexible, Siltek® treated stainless steel
tubing; inertness comparable to fused silica
tubing. See page 118 for our MXT®-200
columns.
*Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced
maximum temperature.

Rtx®-200 Columns (fused silica)
(midpolarity phase; Crossbond® trifluoropropylmethyl polysiloxane)
Rtx®-200/Rtx®-200MS (fused silica)
• General purpose columns for solvents, Freon® fluorocarbons, alcohols, ketones,
silanes, glycols. Excellent confirmation column, with an Rtx®-5 column,
for phenols, nitrosamines, organochlorine pesticides, chlorinated hydrocarbons,
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 trifluoropropyl stationary phase has a unique selectivi-
ty 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.
Rtx®-200MS—Low-bleed GC/MS Columns (fused silica)
(midpolarity phase; Crossbond® trifluoropropylmethyl polysiloxane)
Column specifically tested for low bleed performance.
