Flow of Chemical Analysis

Here is an example of analyzing organic-inorganic composite materials using FT-IR and SEM-EDX. FT-IR measurements were conducted on the glossy and non-glossy areas of the surface of a PET bottle label, revealing that the IR spectra differed between the glossy and non-glossy areas. The non-glossy area is thought to primarily consist of acrylic resin, as its spectrum is similar to that of acrylic resin. Additionally, SEM-EDX measurements were performed on both the glossy and non-glossy areas, and the EDX spectrum and backscattered electron images showed that the non-glossy area contained sulfur (S) and barium (Ba), which were not detected in the glossy area.

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.
