The trace impurities in high purity Te were measured by use of VG9000 glow discharge mass spectrometer (GDMS). Results showed that the stability of analytical performance and the accuracy of analytical results can be assured by means of optimizing the glow discharge conditions and effective eliminating interference. The test results are based on the average value of the three-time tests. The reproducibility and accuracy of the test data indicated that GDMS is a useful tool for elemental analysis of high purity solid samples.
The major and trace level elements in cadmium zinc telluride (CZT) were detected by used of glow discharge mass spectrometry (GDMS). Results show that GDMS is a powerful tool for analyzing trace level elements in solid sample. The semi quantitative analysis can be carried out in the situation of having no standard sample. However, standard sample with the same (or similar) composition must be provided if the major elements want to be known. Only after getting the special relative sensitivity factors (RSF) can the accurate compositions of major elemental be calculated.
