COSMOSIL SL-II-PREP
COSMOSIL SL-II-PREP is ultra pure silica gel packing material more than 99.99% purity. COSMOSIL SL-II-PREP provides improved separation and reproducibility for compounds with carbonyl or phenol hydroxyl groups, which are often problematic on conventional silica gel materials.
*All chromatograms shown below are obtained with silica gel packed into stainless steel columns.
Influence of the particle size on peak shape
The SL-II-PREP is available in five sizes : 3, 5, 15, 75 and 140 µm (particle diameter). The peak shapes depend on the particle size, however, the elution order remains the same.
