The aim of this series of two reviews is to introduce the basic concepts of ICP and GD sector field instruments, to discuss their peculiarities and performance, to present selected analytical applications for demonstration of the 'state of the art' and, finally, to identify possible future trends and developments. Part I focuses on fundamentals, instrumentation and operation of instruments to give an overview of the capabilities of the actual commercially available instrumentation, whereas selected applications will be discussed in detail in part II.

“…Just, a few years after the Element 1 was introduced to the market, Jakubowski and co-workers 391 coupled a high power glow discharge to a prototype of the Element 1 for the analysis of conducting samples. Later also Becker and coworkers 392 coupled an rf-driven GD source to the Element 1. In both cases, the ICPtorch and matching unit were removed and the new GD source was mounted on the existing ICP-interface.…”

Analytical plasma ion sources for elemental mass spectrometry: where are we coming from–where are we going to?

2008

The invention of mass spectrometry at the beginning of the 20th century has had a very important impact on science and technology. In the early days of mass spectrometry a combination of electric and magnetic sector fields was used to separate ions according to their mass to charge ratio and as an ion source a reduced pressure plasma has been applied. Nowadays, plasma source mass spectrometers have become the most powerful instrumentation for inorganic analytical chemistry. The history of plasma source mass spectrometry will be discussed in this article highlighting our own contribution and presenting a personal vision of future application where instrumentation with high mass resolving properties will still play the most important role as to get the highest possible elemental coverage.
