Normal Phase Chromatography
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.

MATERIAL CHARACTERISTICS
 
COSMOSIL 5SL-II

Silica gel

totally porous spherical silica gel

Average particle size

5 µm

Average Pore size

approx. 300m2/g

SCALING UP FROM ANALYTICAL TO PREPARATIVE

Several size are available for COSMOSIL SL-II packed columns for both analytical and preparative applications. Scaling up is straightforward as show below.
