Automatic device for sample treatment and particle analysis, and method for sample treatment and particle analysis

The invention discloses an automatic device for sample treatment and particle analysis, and a method for sample treatment and particle analysis. A sample pretreatment system in the device comprises a sample pretreatment device, an input device for reaction parameter adjustments, a precise quantitative pipetting and adding device, and a reaction control device; a flow cytometry analysis system in the device can acquire the absolute concentration of a certain kind of targets to be tested. The invention further discloses various work modes in which the device is used for the analysis of the targets to be tested. Through the device and the method disclosed by the invention, the processes of marking reactions, hemolytic reactions and the like can be automatically and precisely controlled, and the parameters such as reaction time and reaction dosage can be adjusted by an operator as needed, so that the experiment consistency and repeatability can be ensured; an absolute concentration analysis of the targets to be tested can be carried out without extra labor or equipment.
