| 内容記述 | EDS quantitative analyses were carried out. Ten analysed samples are the pulverized volcanic rocks, whose silica content is in the range of 50 to 75 wt%. The relative errors were positively estimated in the analyses. The standard compositions for the estimation are the values which had been obtained through wet method. After due consideration for the values estimated in various modes of sample preparation, of spectra acquisition, and of data processing, the following are concluded. 1) The adequate accuracy is nearly assured even for the grain size of 100 to 150 mesh, if only the sample would be thoroughly mixed and then homogeneous. 2) The recommended mode of spectra acquisition is the one where a counting time is preset. 3) A least squares fitting method is the best mode of data processing. 4) When the above methods are adopted, the expected relative errors are as follows. As to Si, Al, Fe, Ca, Na and K, those are less than or equal to 5%, and about l0 and 20% for Ti and Mg respectively. | |||||||
