Abstract
A method of distinguishing between fluids may include providing a current to an electrode disposed within a fluidic passageway of a fluidic die, the current to be forced into a fluid within the fluidic die, sensing an impedance at the electrode, and determining a particle vehicle separation level of the fluid based on the sensed impedance between a first instance and a second instance.
