[Data] ICP Emission Spectroscopy Analysis (ICP-AES)

This presentation introduces the composition analysis of cathode active materials using ICP emission analysis. The cathode material of lithium-ion batteries (LIB) is one of the important components that influence the battery's voltage and energy density, and the composition of the cathode material significantly affects the battery's performance. ICP emission analysis allows for qualitative and quantitative analysis of approximately 70 elements, primarily metal elements. It can be applied not only to the composition analysis of LIB cathode materials but also to the qualitative and quantitative analysis of additives and impurities contained in samples, as well as the quantitative analysis of substances regulated by the RoHS directive, among various other analyses.

We would like to introduce our "Chemical Analysis - Trust Us Service." When conducting component analysis of foreign substances or stains on products, it can be challenging to determine whether organic analysis or inorganic analysis is more suitable, and which specific analysis within organic or inorganic is the most appropriate. We provide a comprehensive service for customers who are struggling with the selection of analysis methods. Since each analytical instrument is capable of measuring different targets, it is necessary to choose the method that fits the purpose based on the information available.

We will introduce a case where ICP measurement was conducted using panels before and after reliability testing, along with quantification. The liquid crystal molecules in an LCD are oriented within the panel, and the display is controlled by changes in the orientation state of the liquid crystal due to voltage. When ionic substances, such as metal elements, are present inside the panel, the liquid crystal does not operate correctly, leading to display defects. It is known that ionic substances can increase due to contamination during manufacturing or long-term use, making it important to quantify and understand them as part of panel quality. Metal ions can be quantitatively analyzed using ICP analysis, and depending on the differences in pretreatment methods and detection sensitivity, ICP-AES and ICP-MS are used selectively.

Liquid crystal displays use various organic materials, including liquid crystals, sealing materials, encapsulants, and polarizers. Considering the material properties and degradation mechanisms of each component from a chemical perspective is important for product evaluation and failure analysis. This document presents examples of chemical analysis for the components of liquid crystal displays. 【Chemical Analysis Examples】 ■FT-IR: Principal component analysis ■EDX: Elemental analysis ■GCMS: Liquid crystal component analysis ■HS-GCMS: Outgassing analysis (degradation analysis) and more
