  • Isotopic dilution — is a technique to increase the precision and accuracy of chemical analysis. First, a known amount of an isotope is added to the sample. For example, to determine the amount of lead in a sample, a known amount of Pb 204, one of the isotopes of… …   Wikipedia

  • Isotopic signature — An isotopic signature (also isotopic fingerprint) is a ratio of stable or unstable isotopes of particular elements found in an investigated material. The atomic mass of different isotopes affect their chemical kinetic behavior, leading to natural …   Wikipedia

  • Isotopic labeling — (or isotopic labelling) is a technique for tracking the passage of a sample of substance through a system. The substance is labeled by including unusual isotopes in its chemical composition. If these unusual isotopes are later detected in a… …   Wikipedia

  • isotopic fractionation — ▪ chemistry       enrichment of one isotope relative to another in a chemical or physical process. Two isotopes of an element are different in weight but not in gross chemical properties, which are determined by the number of electrons. However,… …   Universalium

  • isotopic tracer — ▪ chemistry       any radioactive atom detectable in a material in a chemical, biological, or physical system and used to mark that material for study, to observe its progress through the system, or to determine its distribution. An isotopic… …   Universalium
