Derivatization for GC/MS analysis

Proposals 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 according to 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, confirming 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 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.

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; however, analyzing components that do not volatilize upon heating or those with low detection sensitivity is challenging. 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 difficult. However, by performing reactive thermal decomposition GCMS, it is possible to detect the methyl esters of monomers and to separate and analyze them from the additives. Thus, even when the target analytes are difficult to detect using conventional analysis, reactive thermal decomposition GCMS allows for sensitive detection by selecting appropriate reagents for the analytes. [Examples] - Analysis of phthalate esters (DIDP) - Analysis of polymers (polyethylene terephthalate) - Analysis of copper corrosion inhibitors (BTA) *For more details, please refer to the PDF document or feel free to contact us.

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, commonly referred to 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.

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology.

Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily understandable at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
