Methods for Improving the Heating Uniformity of Microwave Digestion Equipment
Compared with traditional graphite digestion or electric heating plate digestion,microwave digestion has the advantages of fast digestion speed,high digestion efficiency,low digestion energy consumption,low sample loss,and full automation.It has been widely used in the field of chemical analysis,such as food,environment,biology,petroleum,metallurgy,etc.The microwave digestion instrument is developed based on microwave digestion technology,but the microwave distribution inside the oven of the microwave digestion instrument is often uneven,which results in uneven microwave heating and low consistency of sample recovery rate.Based on this,a method is proposed to improve the heating uniformity of microwave digestion equipment.By adaptively adjusting the rotation speed of the turntable and the output power of the dual magnetrons,the uniformity of microwave heating is effectively improved,and problems such as melting of the digestion tank,instrument alarm,and inconsistent recovery rate caused by uneven microwave heating are solved.
