Derivatization for GC/MS analysis

Proposal tailored to the purpose of analysis and the target object! GC/MS analysis of derivatized samples.

This document 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 substances is called "derivatization." Methods such as esterification, acylation, and silylation are used selectively based on the type 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, could not be effectively detected without derivatization, but after esterification, trimethyl citrate was detected, proving the presence of citric acid. By performing appropriate derivatization, more accurate analysis becomes possible. [Analyzable substances] ■ High volatility ■ High thermal stability ■ Low polarity *For more details, please refer to the PDF document or feel free to contact us.

Introducing a new device! We present an analytical method aimed at 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.

By adding a special reagent to the sample and heating it, it becomes possible to detect substances that are usually difficult to detect!

In a typical thermal decomposition GCMS, samples are heated to detect volatile components, but it is difficult to analyze components that do not volatilize upon heating or those with low detection sensitivity. Therefore, by adding a special reagent to the sample and heating it, it becomes possible to detect substances that are usually difficult to identify. For example, in the analysis of polymers, thermal decomposition of the polymer results in the detection of a large number of decomposition products, and in some cases, peaks may overlap with other additives, making analysis challenging. However, by performing reactive thermal decomposition GCMS, it is possible to detect the monomer methyl ester and to separate and analyze it from the additives. Thus, even when the target analyte is difficult to detect using conventional analysis, reactive thermal decomposition GCMS allows for sensitive detection by selecting appropriate reagents for the analyte.

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, known 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.

From June 2025, measures against heat stroke in the workplace have become mandatory. Additionally, in December 2026, a "Support Package for Heat Wave Measures in Construction Work" was formulated, making heat stroke prevention during the summer a pressing issue, especially for those engaged in the construction industry. This time, we provide a collection of heat stroke prevention materials that can be utilized through Sysmet Co., Ltd.'s comprehensive weather platform, ZEROSAI X-AI. Examples of heat stroke prevention measures possible with ZEROSAI X-AI: - Cloud management of heat stroke information - Forecasting of the heat index (WBGT) tailored to the site with a mesh of 500m for up to 17 days ahead - Observation of the heat index (WBGT) in compliance with JIS standards using a black globe thermometer - Alerts for exceeding work standard values for the heat index (WBGT) via electronic bulletin boards, emails, and business chat tools like direct LINE WORKS We hope this will be useful at your sites as well.
