Abstract
An automated microwave sample digestion system is disclosed in which a focused microwave digestion system is operated under computer control in association with a computer controlled robotic positioning system such that sample tubes containing samples to be digested are loaded and unloaded into and out from the cooking cavities of the microwave digestion oven in a preprogrammed manner in order to both increase the efficiency of the processing of samples as well as to produce consistent operating conditions for each sample being digested. An additional pump and syringe line is provided for both washing the tube condenser utilized during the digestion process as well as for diluting the digested sample.
