Cation
Exchangers
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 sulfonic groups, usually connected with phenyl
residues. The letter H characterizes a special high sulfonated phenyl carrier
with an exchange capacity of 0.6 mval/g. The letters PM indicate an ES gel,
coated with a polymer layer, with aliphatically connected sulfo groups.

UltraSep ES WCX44
|
|
|
|
Simultaneous separation of alkali and alkaline earth ions in the
presence of ammonia
|
Application KATION1 |
|
Quick
analysis of drinking and industrial water
|
Application KATION2 |
|
UltraSep ES WCX56
|
|
|
Determination of hydroxylamine
simultaneously with ammonia
|
Application KATION3 |
|
UltraSep ES WCXC
|
|
|
In contrast to
the exchangers WCX44 and WCX56 in WCXC the component 18-crown-6 is already
chemically fixed at the silica gel surface together with the exchanger groups (carboxylic
groups). Therefore one can omit addition to the mobile phase. |
