Is there any difference between “spectroscopy” and “spectrometry”?
Many scientists understand ‘spectroscopy’ to mean the general study of spectra, and ‘spectrometry’ to mean the use of spectra for measurement, such as analysis. But this distinction is not universally accepted. In an ISO committee it was recently decided that these two words have been used indiscrimately so often that there is no longer any clear difference between them and therefore either may be used. Hence now Optical Emission Spectroscopy and Optical Emission Spectrometry mean the same thing.
