COSMOSIL 3SL-II 120Å - 3µm

Ultra-pure silica gel of more than 99.99% purity is used for the COSMOSIL SL-II packed column series. This column provides improved separation and reproducibility for compounds with carbonyl or phenol hydroxyl groups, which are often problematic to separate using conventional silica gel columns because of interference of metallic impurities. The followings are applications of COSMOSIL SL-II column on organic acids, acid amides and phenols. COSMOSIL SL-II provides improved separation for these compounds without ionic additives by using mobile phases of hexane and ethanol.
