A multi-channel apparatus for classifying particles according to one or more particle characteristics. The apparatus comprises a plurality of flow cytometry units, each of which is operable to classify particles in a mixture of particles by interrogating a stream of fluid containing the particles with a beam of electromagnetic radiation. The flow cytometry units share an integrated platform comprising at least one of the following: (1) a common supply of particles; (2) a common housing; (3) a common processor for controlling operation of the units; (4) a common processor for receiving and processing information from the units; and (5) a common fluid delivery system. The integrated platform can include a common source of electromagnetic radiation. A method of the invention comprises using a plurality of flow cytometry units sharing the integrated platform to perform a flow kilometric operation, such as analyzing or sorting particles.

The invention discloses a novel magnetic separation mechanism. The novel magnetic separation mechanism comprises a coding turntable mechanism, a magnet opening and closing mechanism and washing mechanisms, wherein the magnet opening and closing mechanism is mounted on the coding turntable mechanism; the washing mechanisms are distributed at the periphery of the coding turntable mechanism; the magnet opening and closing mechanism is used for controlling a magnet to adsorb nano magnetic beads in liquid of a reaction cup on the coding turntable mechanism; the washing mechanisms are used for washing the liquid in the reaction cup to separate the nano magnetic beads. By virtue of the novel magnetic separation mechanism, multi-station separation and washing are carried out by the same mechanism; a uniform mixing station is arranged; the action process of one station and the action processes of other stations can be simultaneously carried out; a magnetic particle mixing mechanism does not need to be arranged outside the mechanism; by virtue of the rotation movement of the coding turntable plate, the magnetic particles can be uniformly mixed according to the principle of the cam movement and the principle of eccentric rotation, so that the action processes are achieved; the novel magnetic separation mechanism is simple in structure; and the separation and washing efficiency of the device is improved.

The invention relates to the technical field of non-continuous enhanced metal-based composite materials, and in particular relates to an in-situ SiC-TiC particle mixing enhanced aluminum-based composite material and a preparation process thereof. For overcoming the defects of high preparation cost, complicated process and poor wettability and compatibility of particles and substrates in the prior art, the invention provides the in-situ SiC-TiC particle mixing enhanced aluminum-based composite material and the preparation process thereof. The preparation process comprises the following steps: firstly, preparing in-situ reaction system press cakes: dividing the designed press cakes into inner and outer layers, wherein the mass ratio of the inner layer to the outer layer is 3:10, and then pressing by a pressure machine; then, preparing Al-4.5Cu based alloy by taking pure Al and Al-50% Cu as raw materials; and finally adding the press cakes in Al-4.5Cu melt to carry out in-situ reaction. Compared with the prior art, the preparation method disclosed by the invention has the advantages that the in-situ produced SiC particles are fine and reach micron scale.
