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. |
