Isotopisk

Isotopisk is an adjective used in Swedish to describe anything related to isotopes—the variants of an element that differ in neutron number. The term stems from iso- meaning equal and -topos meaning place, tracing to the Greek isotopos. In scientific usage, isotopisk describes samples, analyses, or processes that involve isotopic composition or isotope labeling.

Isotopes differ in atomic mass but usually share chemical properties; isotopisk analysis measures ratios such as 13C/12C or 18O/16O to infer age, origin, or environmental conditions. Common techniques include isotope ratio mass spectrometry (IRMS), inductively coupled plasma mass spectrometry (ICP-MS), and laser-based spectroscopy.

Applications span geology, archaeology, hydrology, ecology, medicine, and materials science. Isotopic data help date materials, trace origins, reconstruct past climates, study metabolic pathways with labeled compounds, and track the fate of pharmaceuticals.

Because isotopisk is primarily a linguistic qualifier in Swedish-language science, the English equivalent is isotopic; it is not a separate field but a descriptive term used across disciplines.
