note: In general the blank solution should contain everything that is in the sample except the
colour-producing component. For specific information reference should be made to the procedure or
application being followed. For enhanced reproducibility matched cuvettes should be used.
Scanning the Sample
Once the baseline has been performed the Scan key will be active. Remove the cuvette containing the
blank solution and insert the sample into the sample holder and close the sample chamber lid. Select
the
Scan key, if Auto Scale has been selected once the scan is completed, the screen will blank and
the scan will be re-drawn to the optimum scaling.
