[Data] Analysis of Additive Defects in Polymers Using Thermal Desorption GC-MS

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.

This is an introduction to the analysis of adhesive components in mica sheets using GC/MS. To investigate what components are contained in the mica sheets, spectroscopic measurements were conducted, suggesting that silicone-based adhesives are used. To determine the composition of the silicone-based adhesive, GC/MS measurements were performed. It was found that pentacyclooctasiloxane is used, and it was also discovered that dibutyl phthalate is added as a plasticizer and linear saturated hydrocarbons such as tridecane are added as lubricants.

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
