After reagent and sample are placed, click the “Test” icon in the main menu interface, and then click the cup where the sample is located, the instrument will automatically calibrate and complete the test.

The principle of ion selective electrode testing is based on Nernst equation, so the sample solution must have some ions Strength (cationic > 100mmol/L and anion > 100mmol/L) is required for testing. So sample treatment is divided into two scenarios.

1) Cell culture medium: Since the cell culture medium itself has sufficient ionic strength, it can be directly tested without pre-treatment.

2) Aqueous solutions that cannot meet the requirements of ionic strength:

a: First prepare a solution of 16g/L sodium chloride (which cannot be replaced by other substances) for use.

b: Mix the sample to be tested with the sodium chloride solution prepared in step a at a volume ratio of 1:1 to obtain a mixture with sufficient ionic strength

sample solution.

c: Multiply the result obtained by machine test of the sample solution by 2 to obtain the actual ion concentration of the sample.
