COSMOSIL 5SL-II
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.
