Multi-aperture partition temperature control graphite digester for ICP (Inductively Coupled Plasma)

The utility model discloses a multi-aperture zoned temperature control graphite digester for ICP, which comprises a shell and a controller, the inner cavity of the shell is fixedly provided with a heating mechanism, the heating mechanism comprises a mounting frame, the inner wall of the mounting frame is respectively and fixedly provided with a heat insulation rack and a graphite heating seat, and the heat insulation rack and the graphite heating seat are fixedly connected with the controller. A first placing hole, a second placing hole and a third placing hole are respectively formed in one side of the graphite heating seat, and a graphite electric heater and a thermocouple are respectively and fixedly mounted on the other side of the graphite heating seat. The graphite digester has the advantages of classified sample placement and partitioned heating, and solves the problems that diamond micro-powder with different volumes is inconvenient to place due to the same size of placement holes of the existing grap
