5.4.2 Prepare the measuring cell for the next sample
At the end of this phase, the residue in the measuring cell must be soluble in the next sample. The solubility of
the sample defines if you can drain the measuring cell or if you need to rinse it.
Drain
If the next sample dissolves the sample you just measured, you can drain the cell.
Rinse
If the next sample does not dissolve the sample you just measured, you have to rinse the measuring cell with a
cleaning solution. The cleaning solution must dissolve the sample that you just measured and the next sample.
When you rinse the measuring cell, the cleaning solution removes the residue from the original sample.

5.5 Example: Density determination using the sample pump

The following chapters show you how to configure and perform a density determination of deionized water at
room temperature (23 °C or 73.4 °F).
Summary of the configuration
Guided density determination
•
Filling and draining with the sample pump
•
Evaluation if result lies within specified limits
•
You can find more information about the configuration of a method in the Reference Manual.

Explanation
The density meter prompts users to fill and drain the
measuring cell.
The density meter prompts users to enter the sample ID
before the density is measured.
The density meter prompts users to fill and drain the
measuring cell twice and then fill the measuring cell for
the measurement.
