X-ray emission method


[X-ray spectroscopic analysis]
X-ray spectroscopy is mainly used to analyze elements with large atomic numbers, such as metals. In X-ray emission analysis, atoms in a sample material are excited by irradiating them with an accelerated electron beam, and analysis is performed using the spectrum of the characteristic X-rays they emit. Because a relationship known as Moseley's law exists between the wavelength of the characteristic X-rays and the atomic number, the atomic number of the atoms in the sample material can be determined from the measured wavelength. …

[X線分光分析X‐ray spectroscopic analysis]
 X線を用いた分光分析は,主として金属などの原子番号の大きな元素の分析に応用される。X線発光法では,加速した電子線の照射によって試料物質中の原子を励起し,それが放出する固有X線のスペクトルにより分析を行う。固有X線の波長と原子番号の間には,〈モーズリーの法則〉として知られる関係が成立するから,測定された波長から試料物質中の原子の原子番号を知ることができる。…
