Ultra micro analysis

...The term trace analysis is used to distinguish the latter. In chemical analysis, samples are conveniently divided into macro analysis (up to 0.1g or more), semimicro analysis (10-20mg), micro analysis (up to 1mg), and ultramicro analysis (up to 1μg) depending on the amount of sample handled. Microanalysis was systematized by Austrian chemist Friedrich Peter Emich (1860-1940) around 1926, but major contributions include the development of organic microanalysis by F. Pregl and the development of the spot test by Fritz Feigl (1892-1971).

Japanese:

…とくに後者を区別する場合には痕跡分析trace analysisという用語を用いる。化学分析では取り扱う試料の量により,常量分析macro analysis(~0.1g以上),半微量分析semimicro analysis(10~20mg),微量分析micro analysis(~1mg),超微量分析ultra micro analysis(~1μg)などと便宜上分ける。 微量分析法は1926年ころオーストリアの化学者エーミヒFriedrich Peter Emich(1860‐1940)により系統化されたが,F.プレーグルによる有機微量分析法の開発や,ファイグルFritz Feigl(1892‐1971)による点滴分析法spot test(斑点分析)の開発などが大きな貢献をしている。…
