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. [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, 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.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

Kort Valuta has released a workplace initiative model that leverages points exchangeable for electronic money to support the adoption of safety and wellness habits. Examples include: ・Hydration reporting ・Viewing heatstroke prevention content ・Pre-shift condition checks ・Voice-based condition checks By linking these activities to incentive points, organizations can encourage voluntary participation while supporting workplace safety and employee well-being. The model is designed not only for frontline environments such as: ・Logistics ・Construction ・Manufacturing but also for office-based health and well-being programs. Safety posters and reminders alone are often not enough to drive lasting behavioral change. We hope this initiative provides a practical example for organizations seeking new approaches to workplace safety and employee engagement.
