0.25mm ID Elite-225 Columns

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. In other similar columns, the Carbowax® deactivation layer is not fully compatible with the cyanopropyl siloxane polymer, which can cause tailing of active compounds, and lower efficiency.
Features Temperature Range: 40°C to 220/240°C Equivalent to USP G7, G19 phases	Applications FAMEs and carbohydrates Sterols and flavor compounds
