spectrometry

This term refers to a specialized analytical technique used primarily in chemistry and physics. It is a technical, formal term used in academic and laboratory settings to describe the measurement of spectra. It is often confused with spectroscopy; while spectroscopy is the broader study of light-matter interaction, spectrometry specifically emphasizes the quantitative measurement and the resulting data (the spectrum).

As a field of study or a scientific method, the word is uncountable. It describes a process or a discipline rather than a discrete object, meaning it does not take a plural form in standard scientific usage.
