mass spectrometry

名詞

可算名詞 不可算名詞

(physics, analytical chemistry) An analytical technique that measures the mass / charge ratio of the ions formed when a molecule or atom is ionized, vaporized and introduced into a vacuum. Mass spectrometry may also involve breaking molecules into fragments - thus enabling its structure to be determined.

日本語の意味

質量分析法 – 分子や原子をイオン化し、そのイオンの質量対電荷比を測定することで、化学・物理学的特性や構造を分析する技術。 / 分子のフラグメント化を利用し、構造決定や定量分析に応用される解析手法。

The lab used mass spectrometry to identify trace contaminants in the pharmaceutical sample.

研究所は製薬試料中の微量汚染物質を同定するために質量分析法を用いた。
