[Data] Analysis of Additive Defects in Polymers by 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 analytical instrument is capable of measuring different targets, it is necessary to choose the method that fits the purpose based on the information available.

This is an introduction to the analysis of mica sheet adhesive components using GC/MS. To investigate what components are contained in the mica sheet, spectroscopic measurements were conducted, suggesting that a silicone-based adhesive is 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 revealed 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 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
