Determination of arsenic in biological samples by inductively coupled plasma mass spectrometry with selenium as an internal standard

Method of standard additions for arsenic measurements in water by ICP sector field mass spectrometry at accuracy comparable to isotope dilution

“…The necessity can be avoided by proper application of the internal standard. 30,31 In the present paper we show that the problem can be solved in general, not only for the special case mentioned above. In addition, other forms of application of the method of addition are disclosed.…”

“…The results presented above show good quality of selenium as internal standard for arsenic measurements, in agreement with ref. 30, enabling arsenic concentration determination in the water samples with accuracy comparable to the accuracy of the isotope dilution mass spectrometry. In addition to Se 30,45-47 various other internal standards (Y, In, Ru, Rh, Ga, Ge) 24,26,28,31,41 were used and often a similar effect of the different internal standards was found.…”

“…Examples of detailed arsenic measurement uncertainty analysis can be found. 30,31 Arsenic is a mono-isotopic element and isotope dilution techniques can not be applied in this case. Various matrix effects 24,26,[32][33][34] in addition to numerous spectroscopic interferences in mass spectrometry analysis 11,28 were observed.…”

Environmental applications of single collector high resolution ICP-MS

“…Applying adequate decomposition procedures, HR-ICP-MS has also been successfully employed for the determination of trace elements in diluted digests of a large variety of biological samples including human milk, 168,169 hair, [170][171][172] nails, 171,172 tissue samples such as lung, liver, kidney, muscle, brain and heart, [173][174][175][176][177][178][179][180][181][182] human bones, 183 proteins, 184,185 fish otholiths, 186 fish, 187 Antarctic krill, 188 invertebrates, 189 squid, 190 foraminifera, 191,192 mussels and oyster samples, 193 hemolymph and shell of the common mussel, 194 blood of harbour seals, 195 and zooplankton. 196 Several studies took advantage of laser ablation-(LA-) HR-ICP-MS analysis, i.e.…”

Simultaneous Determination of Arsenic, Selenium and Mercury in Foodstuffs by Chemical Vapour Generation Inductively Coupled Plasma Optical Emission Spectroscopy

“…Finally, due to the increasing demand for routine controls, a fast and multi-elemental analytical method would also be desirable. Many papers have dealt with the quantification of arsenic, mercury and selenium in foodstuffs, focussing on the sample preparation step [5][6][7][8][9][10][11][12][13][14] , the analysis of the digests [15][16][17][18][19][20][21][22][23][24][25][26][27][28] and, in recent years, on element speciation. 1,[29][30][31][32][33] Santos and co-workers 5 compared ultrasonic slurry sampling, ultrasonicassisted extraction and microwave-assisted digestion methods for determination of total arsenic in seafood samples by electrothermal atomic absorption spectrometry (ETAAS).…”
