Metal MXT® Columns
Rugged, flexible, Siltek® treated stainless steel
tubing; inertness comparable to fused silica
tubing. See

for our MXT®-200
columns.
*Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced

Rtx®-200 Columns
(fused silica)
(midpolarity phase; Crossbond® trifluoropropylmethyl polysiloxane)
• 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 an
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, o
Carbowax® phases can not. The Rtx®-200 column offers exceptional thermal stability
low bleed, and superior inertness—even for active compounds such as phenols, an
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.
