Cadmium Electrode

Sample

Look for possible interferences, complexing agents, or substances which could affect the response
or physically damage the sensing electrode (or 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 sections

GENERAL PREPARATION

and
