Abstract
The present invention relates to an apparatus and methods for performing chemical reactions. In particular, the present invention relates to an apparatus for heating chemical reaction mixtures. The apparatus applies one or more semiconductor based microwave generators making the apparatus suitable for parallel processing of chemical reaction mixtures. The invention further relates to methods for performing chemical reactions, e.g. methods for heating a plurality of samples simultaneously or sequentially, methods for monitoring a microwave heated chemical reaction, and methods where the optimum conditions with respect to parameters, such frequency and applied power can be determined for the system consisting of apparatus plus sample.
Claims25
An apparatus for providing electromagnetic radiation comprising:
- a) at least one generator for generating waves of electromagnetic radiation, each of said at least one generators being capable of generating electromagnetic radiation at at least one frequency, where at least one of the generators generates electromagnetic radiation at multiple frequencies at substantially the same time,
- b) at least one guide for guiding at least part of a generated wave of electromagnetic radiation to at least one applicator, and
- c) a controller for individually controlling each of said at least one generators in response to a control signal, the control signal reflecting the status of a sample in the at least one applicator.
An apparatus for providing electromagnetic radiation to a first applicator, said apparatus comprising:
- a) a first generating means for generating electromagnetic radiation,
- b) a first amplifying means for amplifying the generated electromagnetic radiation,
- c) means for guiding the amplified electromagnetic radiation to the first applicator, and
- d) means for controlling the first generating means and the first amplifying means,
- wherein the generated electromagnetic radiation includes a plurality of frequencies generated at substantially the same time, and wherein the first generating means and the first amplifying means are essentially constituted by semiconductor components.
