The liquid presence sensors detect the presence of the samples in the tubing to the flow
cell.
Each liquid presence sensor detects the presence of the front of the liquid moving
through the tubing from the fill cup, and sensor LED changes from red to green. The
time taken for the liquid to reach the sensor is used by the OilExpress 4 software to
calculate parameters, such as the time required for the FCM to pump the sample into
the flow cell and the adaptive cleaning settings.
Only 700 µl of sample is dispensed to the cell.
