Isotope vs. nuclide. A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, whereas the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear. Aug 10,  · Carbon has three main isotopes: carbon, carbon and carbon The first two are stable but the last decays radioactively. In any sample, carbon . The Stable Isotope Facility (SIF) offers analysis for stable isotopes of several light elements (H,C,N,O,S) in a wide variety of sample forms at natural abundance or tracer levels. Most samples can be efficiently analyzed by continuous flow Isotope Ratio Mass Spectrometer (IRMS). A dual inlet IRMS is available for very high precision work. The following analyses are available: Solid samples.

The RSIL provides isotopic calibrations services and materials worldwide. Members of the RSIL also conduct research on the use of isotope-ratio measurements in studies of water resources and environmental quality.

One objective of the RSIL is to develop new techniques for isotopic analysis of oxygen-, sulfur-, carbon-, hydrogen-, and nitrogen- bearing materials. New analytical techniques expand the range of tools available for studying the movement of those elements in hydrologic and biogeochemical systems.

Another objective of the RSIL is to test new applications of isotope measurements in specific field settings. This project also contributes to the improvement of measurement science and the development of isotope databases, as well as providing isotope analyses on a routine basis to a large user community both within and outside of the USGS. Noble gases are a suite of chemically inert elements that are universally present at trace levels in air and water on earth.

As their concentrations are not modified by chemical reactions or microbial activity, they are power indicators of physical processes, including temperature of recharge, gas exchange, diffusion, and transport phenomena. By measuring their concentrations and isotope ratios, we can infer groundwater residence time, recharge temperature, recharge conditions, and gas diffusion processes in the subsurface.
