Abstract:
A device for microwave assisted chemistry and comprising:a cavity with a reaction vessel therein;a source of microwave radiation connected to said cavity for supplying microwaves to a sample in said reaction vessel in said cavity;a resonant inverter for adjustably supplying power to said source of microwave radiation and for defining a duty cycle for said microwave source;means for measuring the duty cycle required to maintain a measured selected parameter of a sample at a predetermined set point while the sample is being exposed to microwave radiation at a first predetermined power level from said resonant inverter; andmeans for moderating the duty cycle to increase the on time of the duty cycle while applying power from said resonant inverter at a second predetermined power level that is sufficient to maintain the sample at the set point using the moderated duty cycle.
