Mass spectrometry, Inductively coupled

Plasma torches and thermal ionization sources break down the substances into atoms and ionized atoms. Both are used for measurement of accurate isotope ratios. In the breakdown process, all structural information is lost, other than an identification of elements present (e.g., as in inductively coupled mass spectrometry, ICP/MS). 

The low concentrations of lead in plasma, relative to red blood cells, has made it extremely difficult to accurately measure plasma lead concentrations in humans, particularly at low PbB concentrations (i.e., less than 20 pg/dL). However, more recent measurements have been achieved with inductively coupled mass spectrometry (ICP-MS), which has a higher analytical sensitivity than earlier atomic absorption spectrometry methods. Using this analytical technique, recent studies have shown that plasma lead concentrations may correlate more strongly with bone lead levels than do PbB concentrations (Cake et al. 1996 Hemandez-Avila et al. 1998). The above studies were conducted in adults, similar studies of children have not been reported. 

Abstract Mobile Au in soil has been postulated for many years. It has been used by the mineral exploration industry in areas of transported overburden as a vector towards buried deposits. Until now, the nature of this mobile Au has not been known or investigated. Soil samples from a colluvial area above the Bounty Deposit (Yilgarn Craton, Western Australia) investigated by analytical techniques including laser ablation inductively coupled mass spectrometry (LA-ICP-MS) and synchrotron x-ray fluorescence (SXRF) combined with X-ray absorption spectrometry (XAS) have allowed us to map the invisible Au in these soils and suggests that at least some of it occurs in an ionic form.

Metals. Although metals analysis has traditionally been carried out using atomic absorption spectrophotometry and more recently inductively coupled mass spectrometry, HPLC can be used in certain circumstances by chelation of the appropriate metal. It would be unlikely that HPLC would be a first choice technique unless it helped to determine... 

Electron ionization usually gives some molecular ions and sometimes these are abundant. Often it is difficult to be certain which ion, if any, is the molecular ion. For this rea.son, it is advantageous to obtain both El and Cl spectra, the first giving good structural information and the second good molecular mass information. g Plasma torches and thermal ionization sources break down the substances into atoms and ionized atoms. Both are used for measurement of accurate isotope ratios.

Inductively coupled mass spectrometry (ICP-MS) has been undoubtedly a hot analytical technique in the last few years. Since the commercial introduction of ICP-MS instruments (VG Elemental Ltd.).in 1983, approximately 150 of them were installed worldwide during the first five years. A number of conferences have been dedicated to ICP-MS, and many analytical and spectroscopic meetings have included an ICP-MS session or symposium. Now two commercial systems (VG PlasmaQuad and Perkin Elmer Sciex ELAN ICP-MS systems) are available.

Technetium isotopes in the PWR primary coolant show a behavior which is quite different from that of the other fission products treated in this section. Whereas the short-lived Tc is only of minor radiological relevance, its long-lived isomer c (halflife 2.1 HP a) deserves some attention with respect to safety analyses for the final storage of radioactive wastes. Normally, c is not analyzed in the reactor coolant because of its very low activity concentration and of its unfavorable radiation properties (P 0.3 MeV, negligible y transition). For this reason, the Tc mass is frequently determined rather than its radioactivity suitable techniques for this task are neutron activation analysis, inductively-coupled mass spectrometry and laser resonance ionization mass spectrometry (see, for example, the comparative evaluation given by Trautmann, 1993). In each case, very expensive analytical procedures are required therefore, the greatest part of the available information on Tc behavior in reactor primary circuits has been derived from measurements of y-emitting Tc.
