3. The fine adjustment is made by way of an energy measurement. Create a
measurement parameter file using the parameters described in Section
"Alignment of accessories", p.9.
4. Change the vertical and horizontal adjustment once more consecutively
until the energy value has reached its maximum size.
Determining the optimum pumping time for the cartridge sipper system
Carry out the optimization of the pumping time with a liquid of similar viscosity
as your sample.
1. Open the measuring parameter window and go to the tab Accessories.
2. Immerse the sample intake hose into the test solution.
3. Switch on the pump with [Pump] and using a stop watch determine the time
required to transport the sample to the cell.
The pumping time is set optimally if approximately 2/3 or the sample have
flown through the cell and 1/3 of the sample still remains in the intake hose
upstream of the cell. This allows the cell to be flushed with the sample prior
to the measurement to minimize carry-over errors.
4. Alternatively to the determination using a stop watch you can also vary the
parameter Pump time.
− Set a pump time in the input field.
− Close the measuring parameter window.
− Start the measurement with .
− Change the pumping time until an optimum sample flow through the cell
is achieved.
