Method and Device for Uniformly Heating a Sample by Microwave Radiation

摘要

The present invention concerns a method and a device for uniformly heating a sample by microwave radiation. According to the invention, at least one stirring element is immersed at least partly in a sample to be heated, said stirring element comprising a magnetic or magnetisable material. A rotating or oscillating magnetic field interacting with said stirring element is generated in a cavity adapted to receive the sample to be heated in order to impart a rotational or translational movement to said stirring element. The rotational or translational movement of said stirring element is contactlessly detected while applying microwave radiation to said sample.
