Biomedical Applications of Isotope-Dilution Liquid Chromatography

Isotope dilution is used to determine the quantity of a chemical substance in a sample. In this method, isotopically enriched material is added to a sample which leads to a “dilution” of the standard. Random sampling is then performed to give the ratio of the standard and sample, which can then be used to infer the quantity of material within the sample. Read more.
