Principle Of Microwave Digestion

Microwave digestion technology uses microwave penetration and activating reaction ability to heat reagents and samples in a closed container, which can increase the pressure in the sample preparation container and increase the reaction temperature, thereby greatly increasing the reaction rate and shortening the sample preparation time. And the reaction conditions can be controlled to make the sample preparation more accurate. Reduce environmental pollution and improve the working environment of experimenters. The traditional method uses a porous digester or a digestion furnace to prepare the sample, and the digestion time of the sample usually takes more than several hours. Even if the more advanced traditional digester is equipped with exhaust gas absorption device, it is difficult to avoid the exhaust gas leakage during digestion and produce a very unpleasant odor. The microwave digestion system is adopted for sample preparation, and the digestion time is only tens of minutes. During the digestion, the digestion tank is completely sealed, so there will be no tail gas leakage, and no toxic catalyst and warming agent are needed. Closed digestion avoids the loss of samples due to the volatilization of tail gas.
