6.4. Changing the Cation Exchanger
The resin of the ion exchanger changes its color from dark violet to
brown if the capacity is exhausted. The resin should be changed be
-
fore no violet resin is left or the cation conductivity rises above the
normal value. At a concentration of 1 ppm alkalization agent, one
resin filling will last for roughly 4 months if sample flow is 10 l/h, or 5
months if sample flow is 5 l/h.
without pre-
rinse option
1
Stop sample flow.
2
Slightly squeeze the exhausted cation exchanger bottle [E] be
-
fore removing.
Thus no water will spill out of the flow cell when loosening the
bottle.
3
Unscrew and carefully remove the exhausted cation exchanger
bottle [E].
4
Fill high purity water into the new cation exchanger bottle [C], un
-
til the water level in the bottle reaches the beginning of the
thread.
5
Carefully, without spilling water, push the cation exchanger bottle
over the inlet filter holder [D] into the bottle holder [B].
6
Screw the cation exchanger bottle into the bottle holder.
Do not tighten the bottle too firmly, this could damage the
gasket.
