Analysis of impurities in organic solvents

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.

This is an example of analyzing impurities confirmed from a solvent when high-purity products are stored in inappropriate environments using liquid injection GC-MS. Ethanol, stored in a light-protective reagent bottle in a cool, dark place, was transferred to a used plastic wash bottle and left at room temperature for about a month. As a result, impurities such as triethyl borate and alkylbenzenes were detected. Additionally, acetone, stored in a light-protective reagent bottle in a cool, dark place, was transferred to a transparent glass bottle without light protection and left at room temperature for about a month, resulting in the detection of diacetone alcohol as an impurity.
