An ultra-pure silica gel of more than 99.99% is used for the COSMOSIL SL-II series of packed columns. Thus, chemical compounds having the carbonyl group and phenol hydroxyl group that could not be clearly separated using conventional silica gel columns can now be separated with better reproducibility and baseline resolution.
