Abstract
A high-frequency induction heater having a working coil for providing a high-frequency application of power to a sample is provided with a control circuit for controlling the amount of power to the working coil. A phase control member can be triggered to provide a first level of power to the sample to heat it below its combustion level, to thereby remove any exterior stains. Subsequently, a second level of power can be applied for a predetermined period of time to heat it to a combustion point whereby the combustion gases of the sample are free from any byproducts of the stain and an accurate measurement can be accomplished.
