Abstract

The latest type of derivatograph, operated by a microcomputer, is described. The equipment is suitable for simultaneous TG, DTG, DTA, TD and EGA measurements under dynamic, isothermal, quasi-isothermal and quasi-isobaric heating conditions. As practical examples, the decompositions of bauxite and manganese(II) sulphate pentahydrate are demonstrated.

Zusammenfassung

Der neueste, von einem Mikrocomputer gesteuerte Typ des Derivatographen wird beschrieben. Mit der Apparatur können TG-, DTG-, DTA-, TD- und EGA-Messungen simultan unter dynamischen, isothermen und quasi-isothermen sowie quasi-isobaren Aufheizbedingungen ausgeführt werden. Die Arbeitsweise wird an Hand der Zersetzung von Bauxit und Mangan(II)-sulfat demonstriert.

Additional information

On the basis of our instructions, the prototype of the apparatus was developed in the Institute for General and Analytical Chemistry, in cooperation with the Hungarian Optical Works, in 1985. The software was designed by P. Somogyvári, G. Veress and T. Domokos, members of the Mathematical Group of our Institute. The computer hardware was prepared by the Institute for Process Control of the Technical University. The equipment is produced by the Hungarian Optical Works, Budapest, Hungary, 1525. P.O.Box 52.
