The
Blank Subtraction
method is used for creating a new baseline for the
instrument for the analysis. It is to be used only when a suspected contaminant
is present in the buffers being used. Performing this will replace the previous
blank.
After each analysis the sonde head and the electrodes are to be washed thoroughly.
This is in order to minimise carry-over and to clean off all traces of the previous
analysis. This can be achieved by using the demineralised water or by washing the
sonde head (without the SAB) in the sample water.
