[Data] Analysis of Polycarbonate Degradation by Reaction Thermal Decomposition
For material evaluation and defect analysis! We will discuss the applied load and degradation mechanisms based on the differences in decomposition products.
Polycarbonate is a material that excels in impact resistance, weather resistance, and transparency, making it widely used in everything from industrial materials to everyday products. However, even polymers with excellent properties can undergo chemical changes, commonly referred to as degradation, due to the usage environment and the passage of time. This document presents examples of degradation analysis of polycarbonate materials subjected to UV irradiation and constant temperature and humidity testing.

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.

Derivatization for GC/MS analysis
This article introduces a pretreatment method to enable the analysis of substances that are difficult to analyze using GC/MS. The pretreatment that converts difficult-to-analyze substances into analyzable forms is called "derivatization." Methods such as esterification, acylation, and silylation are used selectively according to the types and characteristics of the difficult-to-analyze substances. GC/MS measurements were conducted on citric acid solutions and citric acid solutions after esterification. It was found that citric acid, being a carboxylic acid, was not effectively detected without derivatization, but after esterification, trimethyl citrate was detected, confirming the presence of citric acid. By performing appropriate derivatization, more accurate analysis becomes possible.
