equirements for sample and
standard solutions
The requirements for sample solutions and standard solutions are as follows:

Sample solutions shall not contain organic substances. It may cause
electrode deterioration.

The temperatures of sample solution and standard solution shall be kept at
50°C or less. Exceeding 50°C may cause electrode deterioration.

The standard solution in calibration and the sample solution in measurement
shall have almost the same temperature. Match the temperature as close as
possible by, for example, using a thermostatic bath. The temperature
difference may cause measurement error.

The ISA shall be added into the sample solution ( Step 1 of
"Measurement operation" (page 32))
If not, the measurement values may have error. (
“About activity” (page
58)).
