9. A method, comprising:
passing, in serial fashion, a quantity of cells from a cell reservoir to at least one cell sorting device of a microfluidic cell analysis system; and
for each cell sorting device:
detecting cells to be analyzed;
activating a thermal inkjet resistor of multiple thermal inkjet resistors of the cell sorting device, when a cell to be analyzed is detected, to eject the cell to be analyzed, wherein each cell thermal inkjet resistor is individually controllable; and
directing a waste fluid to a waste reservoir, wherein each cell sorting device comprises a sensor per cell thermal inkjet resistor.
