2001年 Mass Spectrometry Reviews (影响因子=10.623,绝对是一流SCI刊物)
有一篇文献谈到 Mattauch-Hertzog 的灵敏度的问题,现摘录如下
In some configuration (Mattauch-Herzog), ions with a wide range of masses are focussed on a plane; this configuration was popularly used in spark source MS and there are research reports on its use with an ICP source, but no commercial instruments have been produced. Even though it has been demonstrated that the Mattauch-Herzog configuration can be used, sensitivity was very poor in experimental instruments.
Multi-Collector ICP-MS avoids the need for magnet changing by incorporating a number of detectors, which allows simultaneous detection, however only over a limited mass range. As mentioned, a Mattauch-Herzog configuration would not have this limitation, but this instrument has not been commercially produced with an ICP source, and the literature report on research instruments had extremely low sensitivity.
