SG Series for protein analysis
By using high-purity silica as support, this series is able to provide good peak shapes for coordinating compounds. The SG300 (wide pore) Series separates proteins and large peptides efficiently, free from their irreversible adsorption.
Features
· Optimum for the analysis of proteins and peptides as well as coordinating compounds
Fig. 1Fig. 1
· A lineup of wide-pore (pore size: 30 nm) phases for various functional groups
· Extended pH range
Polymer coating technology contributes to use in the pH range 2-9
(NH2, pH 2-8)
· USP category
· Also available worldwide
