WebApr 2, 2024 · Step 1: Create space for the source on a workbench Clear up space on a workbench (away from the edges), close to your IRMS where you can place the source and ultimately, replace the filament. Cover the space with a large sheet (s) of aluminum foil atop which the source can be placed. Measurement of natural variations in the abundances of stable isotopes of the same element is normally referred to as stable isotope analysis. This field is of interest because the differences in mass between different isotopes leads to isotope fractionation, causing measurable effects on the isotopic composition of samples, characteristic of their biological or physical history.
