Fortis C18 is used in the analysis of Oseltamivir due to its ability to operate at high pH mobile phase conditions. The official method released from the CDC uses pH10 bicarbonate buffer for the analysis. A 100mm x4.6mm 3u Fortis C18 column provides excellent retention of the Oseltamivir separating it from other components in tablet formulations.
