Electrically non-conductive materials can be analyzed spectrochemically by means of the Grimm discharge lamp after being ground and mixed with a conductive material (e.g. copper powder) and pressed into pellets. Si, Fe, Ca, Al were determined in this way in magnesia-based refractory materials. The influence of the matrix was found to be completely suppressed. |
