SMT Diol column is developed as an alternative for silica column used in normal phase separation methods. The Diol [-OH] functional group is controlled, and as such, provides more reproducible separation when compared to separation on silanols [-OH] from bare silica surface. Furthermore, the hydrogen bonding on the OH functional group on Diol packing material is not as strong as that of bare silica. This results in a reduced interaction of polar compounds on the column. SMT-Diol can be used in normal and reversed-phase separation of pesticides, herbicides, pharmaceutical metabolites, polar natural products, proteins, peptides and other polar biomolecules. Unique features:
Two types of SMT Diol are available:
Just like the silica substrate, both of Diol1 and Diol2 can be subjected to further treatment or modification with another functional ligand for special applications.

SMT SAM Diol – Normal Phase Diol Column
Diol columns for separation of pesticides, herbicides, pharmaceutical metabolites, polar natural products, proteins, peptides and other polar biomolecules. The Diol functional group is controlled, and provides more reproducible separation compared to on bare silica.
Select options -
SMT SAM Diol – Guard Column
Diol Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column.
