Applications of ICP‐MS in Human Biomonitoring Studies

“…These powerful combinations of chromatography and ICP-MS were applied for elemental speciation analysis in clinical samples for several elements (such as As, Cr, Fe, Hg, Mn, P, Pb, Pt, S, Sb, Tl, and V) in hundreds of publications. Some recent reviews to mention are those by Sanz-Medel et al [108], Taylor et al [115], Wrobel et al [116], and Harrigton et al [117]. More information on chemical speciation is given in Chapters 7 and 15 of this book.…”

Atomic Spectrometric Techniques for the Analysis of Clinical Samples

“…According to a recent review, HPLC-ICP-MS is the technique used for more than one half of all speciation studies, although CV for HG and HG for As, S, and Se coupled with AFS and AAS continue to be used [89]. The most studied elements are As, Hg, and Se.…”

Sample Collection, Storage, and Pretreatment in Clinical Chemistry

“…For trace elements, solid phase extraction is primarily employed for preconcentration. Many different materials have been used including charcoal and the walls of dead cells (algae, bacteria), but typical arrangements involve ion-exchange resins often with functional groups added to increase the specificity and capacity of the support [8]. Solid phase extraction can be carried out as an off-line preliminary to the final measurement or coupled to the analytical instrument in a flow-injection (FI) arrangement.…”
