spectrometry
Analyzing electromagnetic radiation
Spectrometry is the measurement and analysis of spectra—the patterns produced when matter interacts with or emits electromagnetic radiation.
Different substances absorb or emit light at characteristic wavelengths, creating signatures that reveal composition.
Mass spectrometry identifies molecules by their mass-to-charge ratio.
The technique is fundamental to chemistry, physics, and forensics: The lab used spectrometry to analyze the sample's chemical makeup.
