1.The concentration of the eluent is not proper.
Solution: Choose proper concentration .
2.The flow rate of the eluentis too high.
Solution: Choose proper flow rate of the eluent.
3.Using samples with excessive concentration
Solution: Dilute the sample.
4.Column is contaminated .
Solution: Regenerate or replace the column.
1.The injection volume of the sample is not constant.
Solution: Inject sample at the volume more than 10 times of the quantitative ring volume to ensure full injection.
2.The concentration of injected sample is improper.
Solution: Select proper concentration of injected sample.
3.The reagent is impure.
Solution: Replace the reagent.
4.Foreign substances exist in the deionized water.
Solution: Replace the deionized water.
5.The flow changes.
Solution: Find out the reasons of such changes and adjust it to the original condition.
6.The flow route is blocked.
Solution: find out the blocked place, repair or make replacement.
1. The reagent is not pure.
Solution: Replace reagents.
2. Deionized water contains impurities.
Solution: Replace deionized water.
1. Incorrect installation of conductivity cell.
Solution: Re-install the conductivity cell.
2. Conductivity conductivity cell is damaged.
Solution: Replace the conductivity cell.
3. The pump has no output solution.
Solution: Check the pressure indication to confirm whether the pump works.
1.Standard solution is contaminated, especially low-concentration samples.
Solution: Re-prepare the solution.
2.Deionized water is impure.
Solution: replace the deionized water.
3.The concentration of the sample is too high or too low, out of the linear range of the device.
Solution: Choose proper range of concentration.
Poor contact of the electrodes.
Solution: replace the power cord or constant current power supply.
