Osaka-Soda C18 KG Series
Osaka-Soda's Capcell PAK C18 KG series is based on an improved silica gel, which has been coated with a new polymer coating. This new polymer coating achieves a pH stability of 1.0 - 12.0. As a result, these phases are used in applications with strongly acidic or alkaline conditions. Due to the high pH stability, these columns can also be used as a replacement for other hybrid phases.
