7.3 Variable Deposition time
The sensitivity of the analysis is controlled by the deposition time which is the
time for which metals are deposited onto the electrode during the analysis.
The relationship between deposition time and sensitivity is linear so doubling
the deposition time will double the amount of metal deposited.
To adjust the deposition time, alter the value in the measurement options box.
If using the standard addition function or calibration the results given in ppb
will be automatically corrected and no calculation is required, although if the
calibration is performed the deposition time must be the same as that for the
consequent analyses.
If using the spreadsheet function it is important to ensure that the deposition
time is kept the same for all analyses.
