“…With regards to nuclear decommissioning, 90 Sr is recognised as a radionuclide of signicant interest. Yanagisawa et al successfully measured pg L −1 levels of 90 Sr combining solid phase extraction with ICP-MS with isotope dilution for stable Sr isotopic ratios ( 86 Sr/ 88 Sr). 204 A combination of solid phase extraction and Dynamic Reaction cell separation achieved isobaric 90 Zr removal of 5.7 Â 10 −9 (Sr/Zr), with a 90 Sr LOD of 1.1 pg L −1 for a 10 mL injection volume.…”

The method was validated using a water sample from the contaminated water storage tank at the Fukushima site, with good agreement between the data obtained using the technique described and from conventional methods.…”

“…The first paper in this section by Hommel et al looked into the continuous measurement of K and S by ETV-ICP-OES to investigate high temperature coal conversion processes . 90 To estimate the fouling, slagging and corrosion potential of a coal during thermal carbon conversion processes, it is necessary to determine the behaviour of elements such as K and S. This study investigated the element release in oxygen-containing atmospheres at varying concentrations.…”

“…While plant materials have been analysed in an ETV-ICP-OES by Detcheva et al, their investigations focus on trace elements with significantly lower concentrations [22]. The most recent works in ETV-ICP-OES analysis by Hommel et al investigate the potassium and sulphur release from coal [23]. However, coal contains significantly lower amounts of potassium and due to the origin, the matrix differs from a typical biomass matrix.…”

The analysis of the chemical composition of biomass plays an important role in all steps of the life cycle of biomass, especially in thermal conversion processes. Electrothermal vaporization (ETV) coupled with inductively coupled plasma optical emission spectrometry (ICP-OES) is a promising approach for biomass analysis as almost no sample preparation is required, samples can be analysed quickly, and the release of elements from the sample can potentially be quantified with temperature resolution. In this work, the concentration of seven important side and trace elements is determined in beechwood, torrefied wood, wheat straw, miscanthus, and spruce bark. For comparison and validation of the ETV setup, four additional methods of analysis are applied to determine the elemental concentration. Chemical fractionation analysis (CFA) is conducted to investigate the chemical association form. In addition, microwave pressure digestion is carried out with two different acid solutions (HNO3 and HBF4). X-ray fluorescence (XRF) analysis is performed to determine the ash composition of all samples. The spread between most of the results of the different measurement techniques is with less than 20 % well within the expected range for heterogeneous biomass samples. Large deviations, such as the sulphur concentration in the XRF analysis, can be explained by the method used. The ETV results are in very good agreement with the CFA and microwave pressure digestion results. As these methods are well established, ETV analysis has proven to be suitable for the analysis of side and trace elements in biomass. Graphical Abstract
