Abstract
Disclosed is a system for setting the timing or phase of the separation of droplets from a fluid stream in a flow cytometer, or the timing or phase of a charge pulse generator, based upon the collected charge of charged droplets. In one embodiment, a conductive mesh can be used to collect the charged droplets that are either deflected or not deflected by the deflection plates. In another embodiment, the charge can be collected from metal plates in the waste collection device. In addition, a defanning device is disclosed that allows substantially uniform deflection of charged cells.
