摘要：

A pressure decomposition device was developed for burning larger amounts of biological or organic matter in a short time in oxygen. The equipment consists of a cylindrical pressure vessel with a safety rapid lock. Thus the vessel can be opened or closed in a few seconds. Construction and good chemical resistance of the used materials allow a high recovery rate of heavy metals like mercury, arsenic, cadmium and lead in concentrations between 50 and 250 ng/g. The equipment can be handled easily. Only cooling water and electric power supply are necessary for operating on a laboratory table. Construction, function principle and conditions of operation are described. © 1979 Springer-Verlag.
