東レリサーチセンター Company Overview

Inorganic element analysis is required in various situations, including understanding the composition of industrial materials and products, the content of impurity elements, troubleshooting in manufacturing processes, and investigating factory wastewater and market products, encompassing research and development, production, and quality assurance. The main methods for inorganic element analysis include Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and Atomic Absorption Spectroscopy (AAS). ICP-OES, ICP-MS, and AAS require the samples to be in solution form for analysis, and sometimes complex chemical pretreatment that requires skill is necessary. In this course, we will provide a basic explanation of the principles, characteristics, measurement procedures, points to note during measurement, and how to interpret spectra for each analytical method. Additionally, we will introduce basic pretreatment methods and processing environments necessary to obtain the solutions required for measurement, as well as points to note during the work. Finally, we will present recent application examples related to ICP-MS.

This course will explain the fundamentals to applications of separation analysis techniques that are essential for the qualitative and quantitative analysis of organic trace components. It will provide a clear introduction to representative methods such as gas chromatography (GC), gas chromatography-mass spectrometry (GC/MS), liquid chromatography (LC), and liquid chromatography-mass spectrometry (LC/MS), including their principles, characteristics, and applicable targets. By incorporating actual measurement examples, the course will clarify the points for differentiating and selecting each method, as well as addressing considerations for improving analytical accuracy and reproducibility. The content is designed to systematically help beginners to practitioners understand the importance of separation analysis, aiming for the acquisition of practical analytical skills.

When conducting structural analysis of organic compounds, IR, NMR, and MS can be considered the three sacred treasures. If the analysis is performed correctly, it is possible to elucidate the structure of even quite complex compounds. However, actual spectra are often not of a single compound, as seen in textbooks, which can lead to considerable confusion for beginners in interpretation. Additionally, while database searches are a useful tool in structural analysis, the ability to read spectra is necessary not only for pattern matching but also for selecting the correct structure from among the candidates. In this course, we will provide lectures that include simple explanations of the principles, basic ways to interpret IR, NMR, and MS spectra, points to be cautious of during analysis, and how to proceed with actual analysis, along with some practical exercises.
