Inductively isotope dilution mass spectrometry IDMS

Several spectroscopic methods have been used to monitor the levels of heavy metals in man, fossil fuels and environment. They include flame atomic absorption spectrometry (AAS), atomic emission spectroscopy (AES), graphite furnace atomic absorption sp>ectrometry (GFAAS), inductively coupled plasma-atomic emission sp>ectroscopy (ICP/AES), inductively coupled plasma mass spectrometry (ICP/MS), x-ray fluorescence sp>ectroscopy (XRFS), isotope dilution mass spectrometry (IDMS), electrothermal atomic absorption spectrometry (ETAAS) e.t.c. Also other spectroscopic methods have been used for analysis of the quality composition of the alternative fuels such as biodiesel. These include Nuclear magnetic resonance spectroscopy (NMR), Near infrared spectroscopy (NIR), inductively coupled plasma optical emission spectrometry (ICP-OES) e.t.c. 

Detailed bulk analysis of environmental samples according to an analytical request. Bulk analysis (see O Sect. 63.5.5) refers to the complete dissolution of the subsample (usually a cotton or cellulose swipe), chemical treatment and measurement of U and Pu by thermal ioni2ation mass spectrometry (TIMS, see Sect. 63.5.5.3) or inductively coupled plasma mass spectrometry (ICP-MS, see Sect. 63.5.5.4). Element concentrations are measured using the isotope dilution mass spectrometry (IDMS) method. In addition to U and Pu, the element Am is sometimes measured using either ICP-MS or alpha spectrometry. 

Inductively coupled plasma isotope dilution mass spectrometry (ICP-IDMS) is a well-known analytical technique based on the measurement of isotope ratios in samples where their isotopic composition was altered by the addition of a known amount of an isotopically enriched element. 

A number of analytical techniques have been used to determine ppm to ppt levels of vanadium in biological materials. These include neutron activation analysis (NAA), graphite furnace atomic absorption spectrometry (GFAAS), spectrophotometry, isotope dilution thermal ionization-mass spectrometry (IDMS), and inductively coupled plasma atomic emission spectrometry (ICP-AES). Table 6-1 summarizes the analytical methods for determining vanadium in biological materials.
