Real-time direct flow measurements to count and sort cells
Flow cytometry is a cell analysis technique that involves generating a uniform, focused flow of cells passing through a laser beam. The scattering of the beam enables cell counting and classification if needed (cell sorters).
Instrument robustness can be affected by pump inaccuracies and oscillations, which lead to uncontrolled flows and eventually a loss of samples and time. Such occurrences, along with other mechanical malfunctions, can impose significant costs for end users.
Real-time direct flow measurements allow the user to measure the volume of sample dispensed. Combined with cell counting, this provides an output in the form of volumetric cell concentration.
Validating the expected pump flow rate, whether it is for the sheath or the sample flow, requires high reliability and repeatability measurements – such as those offered by Sensirion liquid flow sensors. Feedback control can be used by relying on the sensor’s output to ensure the pump performs accordingly.
Relying on microthermal technology, Sensirion sensors offer a highly repeatable flow measurement down to nanoliters per minute and have been used in a variety of analytical laboratory instruments for applications such as liquid handling and pump feedback control.
However, our sensors can do more. On top of flow monitoring, their high sensitivity and fast reaction time enable insights into the instrument’s health and condition by detecting valve ringing, backflow, mechanical wear and bubbles.
