Zusammenfassung:PURPOSE:To carry out the thermal decomposition of a sample rapidly, safely and quantitatively in automatic operation, by a method wherein the heating temp. of the sample is set to optional three stages and the heating time thereof is also set to enable the contorl of the titled apparatus. CONSTITUTION:In an apparatus for thermal decomposition of a sample, a controller 7 consists ofa heating control part for controlling an electric decomposition furnace 3, a supply control part for controlling a pump 16 of an adding mechanism 4 of an oxidizing agent 14 and a discharge control part for discharging mist. In this case, the heating control part is equipped with an apparatus capable of setting a heating temp. to optional three stages and a time setting apparatus setting a heating time every at each set temp. By this constitution, bumping or boiling over of the sample can be prevented and the thermal decomposition of the sample is carried out safely, certainly and quantitatively.
