ICPMS书籍推荐：Practical Guide to ICP-MS By：Robert Thomas
Twenty years after the commercialization of inductively coupled plasma mass spectrometry (ICP-MS) at the Pittsburgh Conference in 1983, approximately 5,000 systems have been installed worldwide. If this is compared with another rapid multielement technique, inductively coupled plasma optical emission spectrometry (ICP-OES), first commercialized in 1974, the difference is quite significant. As of 1994, 20 years after ICP-OES was introduced, about 12,000 units had been sold, and if this is compared with the same time period for which ICP-MS has been available the difference is even more staggering. From 1983 to the present day, approximately 25,000 ICP-OES systems have been installed—about 5 times more than the number of ICP-MS systems. If the comparison is made with all atomic spectroscopy instrumentation (ICPMS, ICP-OES, Electrothermal Atomization [ETA], and flame atomic absorption [FAA]), the annual sales for ICP-MS are less than 7% of the total AS market—500 units compared with approximately 7000 AS systems. It’s even more surprising when one considers that ICP-MS offers so much more than the other techniques, including superb detection limits, rapid multielement analysis and isotopic measurement capabilities.
ICP-MS: RESEARCH OR ROUTINE?
Clearly, one of the many reasons that ICP-MS has not become more popular is its relatively high price-tag—an ICP mass spectrometer typically cost 2 times more than ICP-OES and 3 times more than ETA. But in a competitive world, the street price of an ICP-MS system is much closer to a top-of-the-line ICP-OES with sampling accessories or an ETA system that has all the bells and whistles on it. So if ICP-MS is not significantly more expensive than ICPOES and ETA, why hasn’t it been more widely accepted by the analytical community? The answer may lie in the fact that it is still considered a complicated research-type technique, requiring a very skilled person to operate it.
