The determination of seven arsenic species in seafood was performed using ion exchange chromatography on an IonPac AS7 column with inductively coupled plasma mass spectrometry detection after microwave assisted extraction. The effect of five parameters on arsenic extraction recoveries was evaluated in certified reference materials. The recoveries of total arsenic and of arsenic species with the two...
The determination of arsenic ( 75 As) was studied using an ICP-MS equipped with collision cell technology (CCT). Different mixtures of gases (He and H 2 ) were tested using HCl conditions and a He flow rate of 4mLmin −1 was found to be suitable for the removal of the poly-atomic spectral interference [ 40 Ar 35 Cl] + . Trueness of the optimised method...
The determination of chromium ( 52 Cr), iron ( 56 Fe) and selenium ( 80 Se) isotopes in foodstuffs of animal origin has been performed by collision cell technology (CCT) mode using an inductively coupled plasma mass spectrometry (ICP-MS) as detector after closed vessel microwave digestion. To significantly decrease the argon-based interferences at mass to charge ratios (m/z):...
