isotope ratio mass spectrometry

Isotope ratio mass spectrometry (IRMS) is a scientific technique used to measure the relative amounts of different isotopes of elements in a sample. Isotopes are versions of the same element that have different numbers of neutrons. By analyzing these ratios, researchers can gain insights into various processes, such as identifying the sources of materials, tracing dietary habits in archaeology, or understanding environmental changes. The technique works by ionizing the sample, separating the ions based on mass, and detecting them with high precision, allowing for accurate and detailed analysis of isotopic composition.
