ABSTRACT:
A microwave-based apparatus useful for rapid digestion is provided. The apparatus includes a hollow tubular body having an end sealingly joined to a reaction vessel disposed within a microwave system. The end of the tubular body has grooves for the flow of air through the sealed tubular body/reaction vessel joint. A scrubber removes digestion off gases. Also provided is a rapid, microwave-based, Kjeldahl digestion method.
