Conductivity analyzers are used to measure conductivity in solutions, which is a common method used to determine ion concentrations and solute concentrations in aqueous solutions. Here's how a general conductivity analyzer works:
1.Preparation:
2.Place the conductivity analyzer on a stable work surface and make sure it is connected to a power source and turned on.
3.According to the operating instructions in the instrument manual, install the electrodes and connect them to the instrument.
4.Prepare the sample to be tested and make sure that the sample chamber (electrode slot) is clean and free of impurities and dirt.
5.Calibrate the instrument:
6.Conductivity analyzers are often calibrated to ensure the accuracy of the measurements before they can be measured.
7.Calibration is performed using standard solutions according to the calibration method provided in the instrument manual. There are usually three concentrations of standard solutions for calibration.
8.Prepare samples:
9.Pour the solution to be tested into the sample chamber, making sure the chamber is full, but does not overflow.
10.If needed, diluents or other reagents can be added to the sample to adjust the concentration or properties of the solution.
11.Measuring Conductivity:
12.Insert the sample chamber into the electrode slot of the conductivity analyzer and wait for a certain amount of time for the instrument to stabilize and the measurement to begin.
13.The instrument automatically measures the conductivity of the sample and displays the results on the display. Measurement times may vary depending on the nature and concentration of the sample.
14.Recording of measurement results:
15.After the measurement is completed, the measured conductivity value is recorded. Some instruments may also provide temperature compensation, so care needs to be taken to record temperature information.
16.Measurements can be recorded in paper notebooks, computer software, or data** as needed for subsequent analysis and comparison.
17.Cleaning & Maintenance:
18.After the measurement, remove the sample chamber from the conductivity analyzer and wash and rinse the sample chamber with an appropriate detergent to prevent cross-contamination and sample carryover.
19.Regularly clean and maintain the electrodes and other parts of the instrument to ensure that the instrument is in good working order and to extend its lifespan.
20.Turn off the instrument:
21.At the end of the measurement, turn off the conductivity analyzer and disconnect it from the power supply.
22.If the instrument has a special shutdown procedure or operating procedure, be sure to follow the instructions in the manual.
The above is the operation method of a general conductivity analyzer, and the specific operation steps may vary depending on the instrument model, manufacturer, and application scenario. When using a conductivity analyzer, be sure to follow the instrument closely.
