The feasibility of internal standardization and the oxygen reaction in ICP-MS was studied for accurate determination of boron. Lithium, Be and Rh were systematically evaluated as internal standards (I.S.) for B determination in plants by ICP-MS/MS using a single quadrupole mode and MS/MS mode with O2 into a cell, where B and internal standard signal intensities were processed either after both or only one of them reacted. Carbon is a source of spectral and matrix interferences in B determination by ICP-MS. The use of instrumental strategies such as tandem mass spectrometry (MS/MS) concomitantly with internal standardization demands further investigation about the I.S. behaviour regarding the gas phase reaction with oxygen. The behaviours of B and Be, as well as their oxides, were quite similar in an octopole reaction system containing O2. The coexistence of spectral and non-spectral interferences was evidenced by increasing carbon concentrations in samples and checking positive errors caused for 11B+. Recoveries for B determination in plant certified reference materials without I.S. ranged from 98 to 145% and with Be as an internal standard ranged from 98 to 108%. Beryllium presented favourable characteristics as an internal standard for B due to its mass closeness, similar ionization energy, and reactivity with oxygen. |
