Application of Microwave Digestion Technique in Elementary Analysis

The fundamental principle of microwave digestion technique and its reason to accelerate the degesting speed of the sample were briefly discussed. The equipment and the conponents of the microwave digestion system were introduced.The digesting characteristics of the open-atmospheric vessel and the hermetic-high pressure vessel were compared.The principle and the foundation to establish the digestion method were presented.The application and the recent advance of the microwave digestion technique were reviewed including the determination of trace element,the analysis of forms of metallic element and the auto-test microwave system.
