In addition to our range of silicagels we are offering sulfonated styrene-divinyl resins （GROM Polymer Phases） for the analysis of organic acids, carbohydrates, und sugar alcohols. The resins are ava

All the cation exchangers offered possess chemical fixed exchanger groups and indicate a very good stability within acid media. Weak cation exchangers bear carboxylic groups, strong exchangers sulfon

These anion exchangers are so called ?permanently loaded“ ion exchangers. They exhibit the excellent performance of silicas and the good stability of RP-phases, which leads to low costs.
