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.
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
SMT SAM Diol – Guard Column
Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column.
