Sample
Look for possible interferences, complexing agents, or substances which could affect the response or
physically damage the sensing electrode (or the reference electrode) if the electrodes work perfectly in
the standard, but not in the sample.
Try to determine the composition of the samples prior to testing to eliminate a problem before it starts.
(See
Measuring Hints, Sample Requirements,
and
Interferences
.)
Technique
Be sure that the electrode's limit of detection has not been exceeded. Be sure that the analysis method
is clearly understood and is compatible with the sample. Refer to the instruction manual again. Reread
GENERAL PREPARATION
and
ELECTRODE CHARACTERISTICS.
