...Because there exists a relationship known as Moseley's law between the wavelength of 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-ray emission analysis equipment using a focused electron beam is called an X-ray microanalyser, and is useful for analyzing the local elemental composition of a material. X-ray fluorescence analysis is the same analytical method as X-ray emission analysis, except that the atoms in the sample are excited by irradiation with X-rays, and is also suitable for analyzing metal elements. ... *Some of the terminology used to refer to "X-ray microanalyser" is listed below.

…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。収束した電子線を用いたX線発光分析装置はX線マイクロアナライザーX‐ray microanalyserと呼ばれ,物質の局所的な元素組成の分析に有用である。蛍光X線法X‐ray fluorescence analysisは,X線の照射によって試料中の原子を励起する以外はX線発光法と同一の分析法で,やはり金属元素などの分析に適している。… ※「X-ray microanalyser」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
