Material analysis

Special highly stable ceramics, such as carbide and oxide, are often developed with regard to mechanical and chemical stability. The degree of difficulty to mineralize such materials for the conventional liquid analysis is accordingly high. Often, lengthy digestion methods with complex acid mixtures are required here. In addition, the sample weight for such digestions is usually limited. As a result, the detection sensitivity is often insufficient for the trace range.

This can be avoided with the solid AA^® technology, since the sample merely has to be reduced to a smaller size. The determination of the trace elements then usually occurs without any problems and without much effort. Without diluting
the sample, even the smallest concentrations can be determined reliably.
