equirements for sample and
standard solutions
The requirements for sample solutions and standard solutions are as follows:
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 pH-adjusting ISA shall be added into the sample solution (
Step1 of
" Measurement operation" (page 31)). If not, the measurement can not be
performed accurately.
