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. 

Kelly et al. (NIST) describe an isotope dilution thermal ionization mass spectrometry method for the determination of sulfur in fossil fuels. The method is being used in NIST for certification of a number of liquid fuels at low sulfur concentration levels. Kelly et al. (NIST) also describe a designer calibration standard method for sulfur determination in fossil fuels for users to prepare NIST traceable working standards with known concentrations and uncertainties.
