Elite-225 Capillary Column - 30 m x 0.25 mm I.D. x 0.25 µm

The Elite-225 is a general purpose column for the analysis of FAMEs, carbohydrates, sterols and flavor compounds. The cyanopropylcontaining Elite-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 Elite-225 polymer have increased thermal stability, reduced bleed, and improved inertness. The Elite-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. Equivalent to USP G7, G19 phases.
