isotope dilution mass spectrometry

Isotope Dilution Mass Spectroscopy an overview

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.

Isotope dilution chemistry Britannica

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.

Standard Addition, Internal Standardization and Isotope

Isotope Dilution Mass Spectrometry. As discussed in part 10, ICP-MS suffers form matrix related effects upon the nebulizer and the signal intensity (quenching).In addition, even slight deposition on the sampler cone will cause drifting. Due in part to drifting, analysts have chosen to use the calibration curve technique with internal standardization over the technique of standard additions.
