...There are also limitations to mass measurement, and it is not very effective for quantifying trace amounts of components. Mass spectrometry is a method of quantifying substances using the e / m (charge to mass ratio) of a substance using electric and magnetic fields, but because it can extract a signal as an ion current, it has recently come to be used as an absolute analytical method for measuring trace or ultra-trace amounts of components.

…また質量測定には限界があり,あまり微量の成分の定量には有効ではない。 質量分析計mass spectrometerは電場,磁場を用い物質のe/m(電荷と質量の比)を利用して定量する方法であるが,イオン電流として信号を取り出すことができるので,最近は微量ないし超微量の成分を測定する絶対分析法として利用されるようになった。【綿抜 邦彦】。… ※「mass spectrometer」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 |
