内容記述 | In order to analyze both major and trace elements on a single pellet, it is necessary to prepare a glass bead of as high ratio of sample to flux as 1 : 2. In our laboratory, we determined the operating condition of the bead sampler (Philips-Japan NP1234) by which a glass bead is made under the temperatures less than 1150ーC and the duration of 10 minutes. The weight loss of the bead during the fusion is less than 1%. Vaporization of elements during the fusion is tested to be negligible except for potassium, X-ray intensity of which becomes remarkably lower as the weight loss of the bead increases, so the extent of weight loss must be controlled to be equal among the glass beads. We tested the reproducibility of X-ray intensities on many glass beads and by repeated analyses using the analyzer Philips PW2400 of Shinshu University. A rapid analysis becomes possible with sufficient accuracy, the total time for the analysis of one sample being about 6 minutes. With usage of the Geological Survey of Japan standard rocks as standards, calibration lines are obtained and accuracy of the analysis is shown in Table4. | |||||
