Application Area： Samples treatment by microwave digestion was developed in the last thirty years, it is called microwave chemistry. Put sample and relative reagents in high temperature, high pressure, sealed sample container or open container, under radiation of microwave, according to certain experiment method, by react sample with reagents, violent chemical and physical reaction will take place. This method can be applied to sample preliminary treatment of analytic chemistry such as digestion, extraction, proteolysis, etc. moreover, due to its absolute application predominace, microwave organic synthesis will replace traditional synthesis method. More and more laboratories use microwave digestion system unsteady of time-consuming, difficulty and serious polluted methods to prepare sample for analytic instruments such as AAS, AFS, ICP-AES, ICP-MS, HPLC, GC, etc. Microwave sample treatment system produced by Michem is one of the scientific and technological projects of State Ministry of Science and Technology during the Tenth Five-Year Plan period. Based on learning the advanced technologies from overseas, adopt frequency conversion technique and large furnace chamber microwave oven design. Especially, make a breakthrough in Explosion - proof Safety Technique aspect, and have been patented in China.
