Determination of analyte amount from isotope ratios after adding a known quantity of an enriched isotopic spike and achieving controlled mixing or equilibration.
wp-chem-radiochemistryiaea-neutron-activation-analysisiupac-gold-bookEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
An isotopically enriched tracer supplies the spike in isotope-dilution analysis; accurate inference requires known spike composition, equilibration, ratio measurement, blank correction, and a stated measurement equation.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Isotope dilution infers amount from isotope ratios and a calibrated spike, with the mole supplying the SI amount unit.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
wp-chem-stoichiometryopenstax-chemistry-2eiupac-gold-bookEach relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Mass spectrometry tests an isotope-dilution amount estimate through measured isotope ratios after spike equilibration, blank correction, fractionation control, and a stated measurement equation.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
