mass spectrometry
Ion sorting technique
Mass spectrometry is an analytical technique that identifies substances by measuring the mass of their component molecules.
A sample is ionized and the resulting particles are sorted by mass-to-charge ratio, producing a spectrum that serves as a chemical fingerprint.
The technique is used in chemistry, biology, and forensics to identify unknown compounds, detect trace substances, and analyze complex mixtures: Mass spectrometry confirmed the presence of the drug in his blood.
