4. In a dilution where an unknown sample is pipetted
in less than 5

L, the accuracy of sample injection
volume will be degraded. Input a dilution factor
so that the sample is pipetted in 5

L or more.
5. When a dilution factor is specified in one of Check
Sample and Check Recovery, the value will be
automatically assigned in the other check.

Check RSD:
For RSD judgment, click the check box.

RSD Limit (%):
Input the permissible RSD range of unknown sample.
If this range is exceeded, the sample will be remeasured.
NOTES : 1. When RSD of remeasurement was outside the
permissible range again, the next sample
measurement will be carried out.
2. When the determination mode is set to Simple
STD Add., the first unknown sample will be
excluded from the RSD limit check.
The following messages are printed on the report according to
the settings.

Measured concentration exceeds the useful range of the
working curve. Dilute the sample and measure again.

Concentration of the sample is excessively high. (In the case
where the measurement result even after the dilution is still
outside the range of the working curve.)

RSD exceeds the permissible range. (Processing progresses
to the next step when the re-measurement results are still
outside the range.)
