Field: Measurement (Instruments)
Classification: CPC B  G | IPC G

Claim 8:
9. A particle monitoring system comprising:
a flow passage;
a particle imager to image a targeted particle within the flow passage;
electrodes supported proximate the flow passage;
a power source connected to the electrodes;
a controller to cause the power source to charge the electrodes so as to (1) apply an electric field balanced with respect to gravity so as to hold, levitate and rotate a targeted particle within the flow passage during imaging and (2) release the targeted particle following the imaging;
a particle reservoir;
a stimulant reservoir; and
an inertial pump to selectively draw fluid from at least one of the particle reservoir and the stimulant reservoir into the flow passage while the targeted particle is being held by the applied electric field.
