Attention those struggling with material properties in the manufacturing process at the Institute of Chemical Reaction Mechanisms!

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 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.

Using fragrance as a keyword, we analyzed familiar incense and compared the characteristics of its molecular structure with other materials. The three representative fragrant woods obtained from trees are sandalwood, agarwood, and kyara, but this time we collected data on incense and sandalwood. Characterized by aldehyde groups and aliphatic cyclic structures, the woody scent is primarily believed to be caused by the aliphatic cyclic structure.
