Changing the Ion 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
before no violet resin is left or the cation conductivity rises above
the normal value. At a concentration of 1 ppm alcalizing reagent,
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.
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],
until the water level in the bottle reaches the beginning of the
thread.
5 Carefully, without spilling water, push the cation exchanger bot-
tle 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.
7 Open and adjust the sample flow.
