Common problems of ion chromatograph
High conductivity
1.There are high-conductivity crystals in conductivity cell.
Solution: After cleaning the conductivity cell with 1:1 nitric acid, rinse it with deionized water.
2. The eluent is not pure enough.
Solution: changing the eluent.
3.The chromatographic column absorbs high-conductivity substances.
Solution: Washcolumn repeatedly and alternately with eluent and water.
4. Wrong selection of measuring scale
When conducting positive ions analysis, as the eluate's background conductivity is too high, the selection of too low measuring scale will lead to the indication of too high conductivity value. Just choose the measuring scale again.
5.The suppressor is not working
Solution: Check whether the suppressor is powered on.
6.The sample concentration is too high.
Solution: Dilute the sample.
