Instruction Manual 
 
Cadmium Electrode
 
 
17
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 HintsSample 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
 ELECTRODE 
CHARACTERISTICS.
