The Surface and Bulk Analysis Unit utilizes a variety of analytical instruments to investigate chemical composition, crystal structure, and electronic properties of the samples. My expertise lies in chemical analysis, and one of the instruments I manage is the Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES), which can quantify more than 70 elements simultaneously. When analyzing solid samples with ICP-OES, the sample needs to be completely dissolved in a solution as a pre-treatment. This process ensures that the elements from the solid are fully dissolved and uniformly distributed in the solution, allowing for an accurate assessment of its overall elemental composition. Even with highly chemical-resistant samples, we draw upon years of accumulated knowledge to devise optimal decomposition methods, ensuring complete dissolution. To ensure analytical accuracy, we compare the obtained values with the certified reference materials, which serve as our benchmark for reliability. Some elements are difficult to detect due to spectral interference from other elements or extremely low concentrations, requiring careful evaluation. I will continue honing my skills to adapt to cutting-edge materials and future challenges.
