A technique for determining the unknown quantity of an element of known isotopic composition. A spike, i.e. a known quantity of the same element with a known different isotopic ...

isotope reference standards

Earth science; Physical oceanography

Neither absolute abundances of minor isotopes nor absolute values of isotope ratios can be determined accurately enough for geochemical purposes. As such, differences in such ...
