Isotope dilution mass spectrometry ScienceDirect

1992-9-2  Isotope dilution mass spectrometry (IDMS) is a method of proven high accuracy, which means that it is a technique for which the sources of systematic error are understood and controlled. There are a number of recent papers which deal with the contribution of IDMS to accuracy in trace analysis and with its application for reference measurements [1,2].

Isotope Dilution Mass Spectroscopy an overview

Isotope dilution mass spectrometry (IDMS) is an analytical technique based on the modification of the natural isotope composition of elements or compounds after the addition to the sample of an enriched isotope or an isotopically labeled form of the analyte.

Isotope dilution mass spectrometry: definitive

In this case only we can speak of isotope dilution mass spectrometry. All the advantages and disadvantages inherent to the use of such a molecule as IS are discussed. The use of a calibration curve to perform the quantitative analysis is described, together with the criteria applied for the definition of the reliability of a method (precision, accuracy and limit of quantification).

Isotope-dilution mass spectrometry for exact

Isotopically labeled standards are added in the course of DNA digestion, which allows exact quantification by isotope dilution mass spectrometry. To overcome the major bottleneck of such analyses, we developed a short (~14-min-per-sample) ultra-HPLC (UHPLC) and triple quadrupole mass spectrometric (QQQ-MS) method.
