The Birth of SCX |
|
|
SCX is a polymer-coated strong cation
exchange column that solves the problems encountered with conventional
silica-type ion exchange columns. Precisely classified 5-µm high-purity silica is coated with a thin
film of silicone polymer, and then, followed by the introduction of sulfonic
groups.

Features
|
|
|
- Since high-purity silica is used,
coordinating compounds are not adsorbed.
¡æIrreversible adsorption by complex
formation is not recognized because of small metal impurities in the packing
material.
- Good durability
¡æSi-C bonds used in the polymer film is more
stable than Si-O-Si bonds of conventional silica-based SCX
columns.
- Good lot-to-lot reproducibility
¡æAn excellent reproducibility was obtained
by performing sulfonic group modification on the polymer surface, instead of
doing it directly on silica as conventional SCXs did.
- Utilization of the ion exchange method
with the ion exchange column and the ion-pair method with reversed phase column
based on abundant data
