Component Analysis: GC-MS Gas Chromatography Mass Spectrometer
Introducing a new device! We present an analytical method aimed at the qualitative and quantitative analysis of components contained in samples.
We have introduced the "GC-MS Gas Chromatograph Mass Spectrometer" manufactured by Shimadzu Corporation. This is one of the analytical methods aimed at qualitative and quantitative analysis of components contained in samples, used for the qualitative and quantitative analysis of volatile organic compounds such as parts, materials, residual solvents, and additives. It is necessary for the measurement target to be gasified (with a boiling point below 300°C), but it is suitable for component analysis of mixtures due to its higher sensitivity compared to IR and RAMAN, as well as the ability to separate components in the GC section. 【Overview of GC-MS Equipment】 ■ GC-MS Main Unit: GC-2030, GCMS-QP2020 NX ■ Headspace Sampler: HS-20 ■ Pyrolysis Analyzer: Multi-Shot Pyrolyzer Py-3030 ■ Specifications ・Detection Limit: Several ppm (varies depending on the measurement target) ・Headspace: 40–300°C, Sample Size 13mm x 40mm or smaller ・Pyrolysis Analyzer: 50–1050°C (EGA measurement compatible), Sample Size up to 4mm *For more details, please refer to the PDF document or feel free to contact us.

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.

Analysis of impurities in organic solvents
Here is an example of analyzing impurities confirmed from a solvent when high-purity products are stored in inappropriate environments. 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.

Analysis of fragrance components by GC-MS.
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. For more details, please refer to the related products and catalog below.

Analysis of LCD Display Materials
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 analyses for the components of liquid crystal displays. 【Examples of Chemical Analysis】 ■FT-IR: Principal component analysis ■EDX: Elemental analysis ■GCMS: Liquid crystal component analysis ■HS-GCMS: Outgassing analysis (degradation analysis) and others
