Abstract:
1. A system comprising: a fluidics system comprising a rack adapted to receive at least one sample container containing a preliminary sample, and a fluid transfer device, the fluidics system being adapted for relative movement of the fluid transfer device and the rack and for fluid communication between the fluid transfer device and the sample container, the fluid transfer device comprising at least one of a fluidics head and a pipetting apparatus; a sensor device configured for measuring a concentration of particles in the preliminary sample and communicating the concentration; and a controller device in signal communication with the fluidics system and the sensor device; the controller device adapted to receive the measured concentration of particles in the preliminary sample from the sensor device; the controller device being further adapted to determine an amount of diluent to be added to the sample container or an amount of the preliminary sample to be removed from the sample container by the fluid transfer device to prepare a sample having a selected concentration of particles; and the controller device being further adapted to control the fluid transfer device to add the determined amount of diluent to the sample container or to remove the determined amount of the preliminary sample from the sample container so as to prepare the sample having the selected concentration of particles.
