    Abstract: A pulsation attenuator for a fluidic system with a fluidic pump. The pulsation attenuator includes a fluidic channel, a first fluidic device adapted to attenuate pulsations with a shallow rolloff slope, and a second fluidic device adapted to attenuate pulsations with a shallow rolloff slope. The first fluidic device and the second fluidic device are connected to the fluidic channel such that they cooperatively attenuate pulsations with a steep rolloff slope. Preferably, the first fluidic device includes a first fluidic resistor and a first fluidic capacitor, and the second fluidic device includes a second fluidic resistor and a second fluidic capacitor. Preferably, the pulsation attenuator is arranged, similar a second-order low-pass filter, in the following order: (1) first fluidic resistor, (2) first fluidic capacitor, (3) second fluidic resistor, and (4) second fluidic capacitor.

    Abstract: The fluidic system of the preferred embodiment includes a sheath pump to pump sheath fluid from a sheath container into an interrogation zone, a sheath volume measurement device to measure the fluid in the sheath container, a waste pump to pump the sheath fluid and a sample fluid as waste fluid from the interrogation zone into a waste container, and a waste volume measurement device to measure the fluid in the waste container. The system also includes a controller connected to the sheath pump, the waste pump, and the volume measurement devices. The sheath pump and/or the waste pump draw sample fluid from a sample container into the interrogation zone, which functions to provide a location for the fluidic system and an optical system of the flow cytometer to cooperatively facilitate the analysis of the sample fluid.
