SIRIS (Stable Isotope Ratio Mass Spectrometer)

A SIRIS (Stable Isotope Ratio Mass Spectrometer) is a scientific instrument that measures the relative amounts of different forms (isotopes) of elements, like carbon or nitrogen, in a sample. By analyzing these ratios, scientists can gain insights into processes such as climate change, food origins, or environmental conditions. The device separates isotopes based on their mass and detects their proportions precisely, providing valuable data for research across various fields. Essentially, it helps researchers understand the history and sources of substances by examining their isotopic fingerprints.
