  • Patent number: 10221844
    Abstract: A fluid handling system for a particle processing instrument includes a pump, a pulse attenuator, a pressure transducer, and a pump controller. The pump may be configured to supply a pulsed flow of fluid having a first pulse characteristic to the pulse attenuator. The pulse attenuator may have a single, undivided, volume, fluid inlets, fluid outlets, and a pressure sensor port. The pulse attenuator may supply an outlet flow of fluid having a second pulse characteristic different from the first pulse characteristic. The pressure transducer may be in fluid communication with the pressure sensor port and in control communication with the pump controller. The pump controller may be in control communication with the pump to maintain a substantially constant nominal pressure within the pulse attenuator by controlling the pump motor.

  • Patent number: 10025322
    Abstract: A fluid handling system for supplying a working fluid to a fluid flow instrument is disclosed. The system includes a controller configured to receive sensor signals indicative of a deformation of a flexible barrier located between a control fluid volume containing a control fluid and a working fluid volume containing the working fluid. Based on the sensor signals, the controller may send signals to control the operation of a working fluid flow generator in order to regulate or control the fluid characteristic of the working fluid being provided to the fluid flow instrument.
