polar phase; Crossbond cyanopropylmethyl phenylmethyl polysiloxane The cyanopropyl-containing Rtx-225 phase is slightly less polar than bonded polyethylene glycol (PEG) phases, but it can be used for many of the same applications. Improvements to the Rtx-225 polymer have increased thermal stability, reduced bleed, and improved inertness. The Rtx-225 column provides a 20°C thermal stability advantage over other "225" columns because of our unique polymer synthesis technology and proprietary siloxane deactivation. In most similar columns, the Carbowax deactivation layer is not fully compatible with the cyanopropyl siloxane polymer, which can cause adsorption, tailing of active compounds, and lower efficiency. General-purpose columns for FAMEs, carbohydrates, sterols, flavor compounds. Equivalent to USP G7, G19 phases.
