Abstract:The fundamental principles and analytical methods of the original position analysis (OPA) with spark source spectrometry are introduced.The application of such a technique is exemplified by the analysis for determination of concentration distribution of elements,segregation of elements and defect discrimination on bloom sample surface.It is demonstrated that the OPA with spark spectrometry is unique and superior to other traditional spectrometric methods in its precision of measurement,speed of analysis and visual representation of results.
Keywords:original position analysis  segregation  inclusion
