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.

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.

"Somewhat inconvenient" can quickly transform into "cost" and "risk" due to an increase in the number of employees or an expansion of business scope. What we are introducing this time is the process of a home care industry company with around 700 employees verbalizing their frustrations regarding payroll operations and considering the optimal system configuration. When we verbalize "somewhat inconvenient"... 1) The support quality of the payroll system being used is poor, causing significant stress. 2) The number of employees has been on the rise in recent years, raising concerns about running costs due to the pay-per-use system. 3) Macros are being used for data integration with a separate system. 4) We want to make backend processes like payroll payment reports easier.

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.

Caught up in daily data entry, approvals, and inquiries, I want to improve but can't find the time to consider it. Such voices from the field are not uncommon. Even though it's clear that systemization is necessary, the reality is that people often get stuck on where to start and which products to choose. Common frustrations include "I spent time requesting materials and demos, but I'm not sure if it fits my company," and "After implementation, the inquiry contacts are scattered among different manufacturers, making it hard to connect quickly when issues arise." This moves us further away from the original goals of efficiency and reducing dependency on individuals. This is where the option of "agent implementation" comes into focus. Agents that handle products from multiple manufacturers have the advantage of providing unbiased comparisons and neutral proposals without favoring specific products. Even within the same category of systems, they can present the pros and cons side by side for a balanced evaluation. There is also a common misconception regarding pricing; in most cases, there is little to no price difference between direct sales from manufacturers and agents.
