Isotope dilution, radiochemical method of analysis for measuring the mass and quantity of an element in a substance. The procedure involves adding to a substance a known quantity of a radioisotope of the element to be measured and mixing it with the stable isotope of the element. A sample is then taken from the mixture and analyzed.

13.3.3.2 Isotope dilution mass spectrometry. Isotope dilution mass spectrometry (IDMS) is based on the fact that many elements have two or more stable isotopes whose proportion in nature is constant. A known amount of a stable isotope is added to a sample and the ratio between the isotopes can then be measured by MS.
Methods: An isotope-dilution liquid chromatography/mass spectrometry (ID-UPLC-MRM) assay was developed using (13)C6-glucose as a stable isotope analogue to specifically measure glucose concentration in human plasma, and validated for use against NIST standard reference materials, and against fresh isolates of whole blood and plasma into which ...
Isotope dilution mass spectrometry (IDMS) is used extensively at NBS in the certification of ele-mental concentrations in Standard Reference Ma-terials. It is regarded at NBS as a "definitive method," that is, a method of proven high accu-racy. Since the theme of this symposium is accu-
Isotope dilution inductively coupled plasma-mass spectrometry (ID ICP-MS) has been applied for the determination of the total mass fractions of five trace elements (Cd, Cu, Hg, Pb, and Zn) and ...
Isotope Dilution Mass Spectrometry (IDMS) has become an essential tool in research laboratories and is increasingly used in routine analysis labs (including environmental, food safety and clinical applications). This is the first textbook to present a comprehensive and instructive view of the theory and applications of this growing technique.The main objective of this book is to cover the ...
Isotope dilution mass-spectrometry can be applied to the determination of minute amounts of calcium in distilled water, deionized water and snow melts from ice sheets in Greenland and Antarctica. The amount of sample required is 20 g for snow analysis. In a 100-ml teflon beaker, 0.3 x 10/sup -7/ M of /sup 12/Ca spike in 0.06 g of dilute nitric ...

The MRM approach combined with stable isotope dilution–mass spectrometry (SID-MS) can be used to develop multiplexed, high throughput, accurate and sensitive assays for a moderate number of candidate biomarkers (30-100) and applied to a large number of samples.
The method was validated by species-specific isotope dilution gas chromatography/mass spectrometry (GC/MS) analysis of constituent amino acids of the target peptide. Quantitative labeling of bradykinin peptide was accomplished with a commercially available 2′,2″-(10-(2-((2,5-dioxopyrrolidin-1-yl)oxy)-2-oxoethyl)-1,4,7,10 ...

1.1 This method consists of two approaches: (1) isotope dilution mass spectrometry (IDMS) for the determination of the total concentrations of elements and molecules and (2) molecular speciated isotope dilution mass spectrometry (SIDMS) for the determination of elemental and molecular species.
Isotope dilution mass spectrometry as a primary method is one of the option for this purpose. In this study, triethylamine (TEA) assisted Mg(OH) 2 co-precipitation is developed and combined with isotope dilution mass spectrometry for the characterization of candidate certified reference material, UME CRM 1206.
At present, the only analytical principle that appears to be suitable for establishing such a reference procedure is isotope dilution mass spectrometry (ID-MS). 1 Björkhemet al.

In the past isotope dilution mass spectrometry (IDMS) has usually been applied using the formation of positive thermal ions of metals. Especially in calibrating other analytical methods and for the certification of standard reference materials this type of IDMS became a routine method. Today, the progress in this field lies in the determination of ultra trace amounts of elements, e.g. of heavy ...
