The invention relates to an integrated closed sample dissolving
system and method, belongs to the technical field of sample dissolving devices, and solves the problems of complicated operation steps,high operation intensity, low experiment efficiency, various used equipment / devices, large occupied space and environmental
pollution of an existing sample dissolving device. The integrated closed sample dissolving
system comprises a sample dissolving tank, a heating table and a fixed sealing
assembly, wherein the sample dissolving tank comprises a tank body and a cover body; the heating table isprovided with a sample dissolving tank mounting hole; and the fixed sealing
assembly comprises a fixed cover plate and a closing bolt, the fixed cover plate is located above the heating table and connected with the heating table, the fixed cover plate is provided with a first screw hole, and the closing bolt abuts against the cover body through the first screw hole. The
system integrates the functions of sample dissolving, acid driving and redissolving, realizes sample dissolving, acid steam collection treatment and redissolving under a closed condition, has the advantages of simple structure,small size, less used equipment, low operation intensity, high experiment efficiency and low cross
contamination risk, and has great popularization potential.
