電磁鋼片中微量元素分析* * Trace Element Analysis in Electric Magnetic Steel Sheet  2 2   2 2  S.H.Chen J.Y. Peng B.C. Leu Y.S. Hwang The qu ality of electr ic m agnet ic st eel is affected by its trace element content. To reduce the residual content in the steel making process, Sp ark-AE S we need to control the scrap addition with fast ICP-OES and accu r at e on -lin e an aly sis. In th is r ep or t ICP-MS we will discu ss the accuracy of trace element an aly si s in Sp ar k-A E S, t h e c omp ar i son of analysis results in ICP-MS, ICP-OES and Spark- ICP-M SSpark OES, and the discrepancies in different digestion Spark methods. 關鍵字： key words: Electric magnetic steel Trace element analyeis, ICP-MS, ICP-OES, Spark-OES 壹、 前　言 SAl+V+Ti Spark-OES Spark ICP-OES ICP-MS Spark-OES ICP-MS ICP -OE S * Paper presented at 2006 CIMME Annual Convention, October 5, 2006, Taipei .
