He developed the Mattauch isobar rule in 1934. ==Mattauch–Herzog geometry mass spectrometer== One of Herzog's most important contributions to mass spectrometry was the design of a sector mass spectrometer. The Mattauch–Herzog geometry consists of a $\backslash pi\; /\; 4\backslash sqrt$ radian electric sector, a drift length which is followed by a right angle ($\backslash pi\; /\; 2$) magnetic sector of opposite curvature direction. The entry of the ions sorted primarily by charge into the magnetic field produces an energy focussing effect and much higher transmission than a standard energy filter. The advantage of this geometry is that the ions of different masses are all focused onto the same flat plane, which allows the use of a photographic plate or other flat detector array. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Josef Mattauch」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
