Flow-through, microwave-heated digestion chamber for automated sample preparation prior to inductively coupled plasma spectrochemical analysis

Abstract

A microwave-heated, flow-through digestion device was designed for a commercial, focused microwave system and applied to the on-line preparation of biological samples including milk, whole blood and urine. Accurate and precise results were obtained by inductively coupled plasma atomic emission spectrometry with solutions prepared by on-line stopped-flow digestion.
