Effect of Sample Matrix on Radial and Axial Profiles of Ion Abundance in Inductively Coupled Plasma Mass Spectrometry
TL;DR: In this paper, the effect of various concomitant elements in inductively coupled plasma mass spectrometry (ICP-MS) analysis was assessed by measuring the distribution of selected singly charged analyte ions (Al, V, Cr, Mn, Ni, Co, Cu, Zn, As, In, Ba, La, Ce, Pb), doubly charged ions (La, Ce), Ba and Pb) and oxides ions (BaO) in the presence of concurrency elements spanning a mass range from 23 (Na) to 133 (Cs) u
