[Data] ICP Emission Spectroscopy Analysis (ICP-AES)
We will detect and analyze the atomic emission that occurs when an atom returns from an excited state to its ground state!
In ICP emission spectroscopic analysis, it is possible to detect multiple metal elements contained in a sample simultaneously. This document introduces examples of the analysis of trace metal elements contained in liquid crystals. It includes the principles and overview of ICP-AES analysis as well as measurement examples. Please feel free to contact us regarding the sample state or the elements to be analyzed.

Composition analysis of LIB cathode active materials by ICP luminescence analysis.
This presentation introduces the composition analysis of active materials in cathode materials using ICP emission analysis. The cathode material in 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. In addition to composition analysis of LIB cathode materials, it can also be applied to various analyses, including qualitative and quantitative analysis of additives and impurities contained in samples, as well as quantitative analysis of substances regulated by the RoHS directive.

Chemical Analysis Concierge Service
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 analysis device can measure different targets, it is necessary to choose a method that fits the purpose based on the information available.

Analysis of trace metal elements in liquid crystals
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 may not drive 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.

Analysis of LCD Display Materials
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 analyses for the components of liquid crystal displays. 【Examples of Chemical Analysis】 ■FT-IR: Principal component analysis ■EDX: Elemental analysis ■GCMS: Liquid crystal component analysis ■HS-GCMS: Outgassing analysis (degradation analysis) and others
