Paper published: Analysis of TCEs in plant reference materials

The validated measurement procedure applied for all plant samples of the project was published in Analytical and Bioanalytical Chemistry in a paper entitled “Determination of 48 elements in 7 plant CRMs by ICP-MS/MS with a focus on technology-critical elements” by Simone Trimmel, Thomas C. Meisel, Shaun T. Lancaster, Thomas Prohaska and Johanna Irrgeher (all Montanuniversität Leoben): https://link.springer.com.

7 plant certified reference materials (CRMs) were analysed for their mass fractions of 48 elements, with a particular focus on TCEs, namely Li, Be, Ga, Ge, Nb, Sb, Ta, Tl, Bi and the rare-earth elements (REEs, i.e., lanthanides and Y). The selected CRMs cover different kinds of plant matrices and a wide range of mass fractions. After microwave-assisted digestion of 16 replicates of each CRM with HNO3, H2O2 and HBF4, ICP-MS/MS analysis with N2O as cell gas was performed.

In addition to providing an optimised measurement procedure for rarely studied elements, the article improves the characterisation of commonly used plant CRMs.
