...Depending on the amount of sample handled, chemical analysis is 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). Microanalysis was systematized around 1926 by Austrian chemist Friedrich Peter Emich (1860-1940), but major contributions include the development of organic microanalysis by F. Pregl and the spot test by Fritz Feigl (1892-1971). In organic microanalysis, elemental analysis can be performed using 3-5mg of sample, and in spot analysis, the target chemical species can be analyzed using one drop of sample (0.05ml). ... *Some terminology explanations that mention "spot test" are listed below.

…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。有機微量分析では3~5mgの試料を用いて元素分析ができ,点滴分析では1滴の試料(0.05ml)で目的化学種を分析することができる。… ※「spot test」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 |
