Abstract

See full text

The manufacturing of a furnace for electro-thermal atomization of samples for spectroscopical purposes having a cavity for the accommodation of sample is simplified and improved. To this end, the furnace consists of two halves which are joined along a separating plane intersecting the cavity. The furnace is made of graphite and provided with a layer of pyrolytic graphite. A platform for the accommodation of the sample is integral with one of the halves. A method for the production of such a furnace comprises the method steps: (a) producing two blank parts which engage each other with planar surfaces; (b) machining the two blank parts in common so that a cavity intersected by the plane of the planar surfaces is generated and each of the blank parts forms one half of the furnace; (c) separating the two halves of the furnace which were produced in this way; (d) coating the halves of the furnace separately, the inner surfaces of the cavity forming outer surfaces of each of the two halves of the furnace; and (e) joining the halves of the furnace, generated in this way, to a furnace. There is also a method described for decreasing the refuse in the manufacturing of the furnaces.
