Rtx-200 columns have accomplished many difficult separations. The trifluoropropylmethyl polysiloxane stationary phase has a unique selectivity that changes elution orders and resolves compounds that phenyl, cyano, or carbowax phases can not. These columns offer 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.
