Isotoopianalüüsiga

Isotoopianalüüsiga refers to the analysis of isotopes, which are atoms of the same element that have different numbers of neutrons. This difference in neutron count leads to variations in atomic mass, while the number of protons, which defines the element, remains the same. Isotopic analysis leverages these mass differences to provide valuable information about the origin, history, and processes related to a sample.

The principle behind isotopic analysis involves measuring the relative abundance of different isotopes within a sample. This is typically achieved using mass spectrometry, a technique that separates ions based on their mass-to-charge ratio. By comparing the measured isotopic ratios to known standards or expected ratios, scientists can infer a great deal. For example, the isotopic composition of water can reveal information about its source and the climate conditions under which it formed. In archaeology, the isotopic signatures of human or animal remains can indicate diet and geographic origin. Forensic science uses isotopic analysis to trace the provenance of materials or to identify substances. The field also plays a crucial role in environmental studies, geochronology, and nuclear science.
