COSMOSIL SL-II HPLC Columns

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. The COSMOSIL SL-II columns are available in particle sizes 3 μm, 5 μm and 5 μm.
