Stability criteria
The following stability criterion must be met to obtain a stable electrode response
during 1- and 2-point
calibration:
pH(limit)i).updpH(sample,last).updpH(sample, ≤−
The following stability criterion must be met to obtain a stable electrode response
during
measurement:
pH(limit)i).updpH(sample,last).updpH(sample, ≤−
where:
pH(sample,upd.last) = pH value from the last updating with a measurement
on calibration solution or sample. (The last updating
is number 30).
pH(sample,upd.i) = pH value for a given updating with a measurement
on calibration solution or sample. (The relationship
must be fulfilled for at least one of the updating
numbers 20 or 21).
pH(limit) = pH limiting value for the stability criterion (0.005).
