Spectrometry in the Analysis of High Purity Materials

Spark source mass spectrometry (SSMS) and atomic absorption spectrometry (AAS) have played important roles as powerful analytical tools. Both these techniques have undergone significant improvements since the late fifties in instrumentation and methodology leading to their application in various branches of science and te chnology. These techniques can be regarded as complementary techniques in the analysis of high purity metals, semi-conductors and also non..conducting powders. SSMS is caiable of analysing al most all elements at parts per billion levels, semi-quantitatively as a survey analysis and AAS can be employed to analyse for several elements with the required precision.
