摘要： The invention relates to a method and to a device used to carry out a flow cytometry method, preferably intended for, but not limited to, the counting and differentiation of white blood cells. More specifically, the invention relates to the field of simplified hematology devices with low operating costs. According to the invention, the method is characterised in that an impedance measurement technique is used to identify particles having a trajectory that has not passed through a predetermined optical measurement area so as to treat said particles selectively, thereby eliminating the use of sheath fluids in order to guide the particles toward the measurement area.
