Spark source mass spectrometry (SSMS) is used to analyze metallurgical grade silicon powder, which has been submitted to different purification steps. The principal advantage of this method in comparison to other analytical methods is the broad range of impurity elements detected simultaneously in each analysis. By using self-prepared standards relative sensitivity factors for 35 impurity elements have been determined to enhance the accuracy of the results: concentration values for most elements are expected to be accurate within a factor of 2. 3 refs.
