Cosmosil SL-II Packed Columns

Click for Application Data

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