Sepax Polar-Pyridine Columns
Description
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents,
Polar-Pyridine phase is bonded with ethyl pyridine functional groups. With a polar and N-containing
ring structure, Polar-Pyridine phase is slightly basic and adequate for many applications, such as
pharmaceuticals, peptides, sugars, and nucleotides.
