Abstract:
A method of controlling a microwave heated chemical process comprising the steps of:placing one or more sealed vessels in a microwave chamber, the vessels provided with a resealable venting vessel cover and containing one or more chemical chemical substances in the chemical process;sensing a chemical substance diffusing through vessel walls or realeased from the resealable venting vessel cover within gases in one of the microwave chamber and the microwave exhaust system and providing a signal based on a concentration of the sensed chemical substance at a first time;sensing the chemical substance within gases in one of the microwave chamber and the microwave exhaust system and providing a signal based on a concentration of the sensed chemical substance at a second other time;analyzing the signal to determine a change between the sensed concentration of the chemical substance at the first time and the sensed concentration of the chemical substance at the second time; and,in response to a determined change, automatically performing one of reducing microwave radiation energy by an amount less than the current microwave radiation energy level and increasing microwave radiation energy.
