Performance gaps in the industry's earliest miniature spectrometers today have been mitigated by the ongoing improvement of gratings, coatings, mirrors, and other spectrometer bench optical components.
The ultimate in atomic spectroscopy performance, magnetic sector inductively coupled plasma-mass spectrometery (ICP-MS) instruments are used for the most demanding analyses. There is significant demand across several industries, despite the fact that the global market for such instrumentation is a niche area.
In the previous installment of this column, David Ball introduced the five types of symmetry elements that are important in physical science. Here, he discuss why it’s called "group" theory in the first place.
