ABSTRACT:
A digester-evaporator for partially digesting a sample and for evaporating the solvent after partial digestion. The digester includes at least one reaction coil; a heating element arranged along a portion of the reaction coil; at least a portion of the reaction coil proximate to its output being preheated by the heating element to a degree sufficient to convert a partially digested sample into vapor; a collector spoon with carrier water for collecting sample vapor; and an evaporator portion including an evaporation chamber including a substantially vertically-oriented tube The collector spoon is arranged in the top of the substantially vertically-oriented tube, and a gas supply tube for supplying a preheated gas provided in a top of the substantially vertically-oriented tube so as to create a cyclonic gas flow into the chamber and carry the sample to a container area in a bottom portion of the chamber.
