Working with SOPs NanoPlus Operator’s Manual
4-6 Mar 2014
Using the SOP Designer for Other Functions
You can also use the SOP Designer > Cell Parameters to detect the optimal cell position, and
measure the cell constant and electrical conductivity.
Detecting the Optimal Cell Position
The measurement cell can be positioned in order to obtain an optimum intensity for measurement,
and the value saved in the cell parameter.
You should perform a Cell Center adjustment:
• when a new cell parameter is created
• the first time a cell is used in a measurement
• if the concentration or sample type changes
You can repeat the adjustment if the intensity monitor shows the sample concentration is too low.
1. In the Cell Parameters panel, click Adjust Cell Center from the Task options; the Cell Center
Detection dialog is displayed.
2. Click Start . The optimal position for measurement is detected automatically, depending on
the selected cell type. After the detection has been completed, the results are displayed in the
Result section. Also shown are the:
• variation of intensity of the cell position
• attenuator percentage
• previous and new cell centers
3. Click OK to store the calculated cell position in the cell parameters. If you click Cancel , the
previous center remains stored as-is, and the cell moves to that position.
