Analysis of impurities in organic solvents

The aldol reaction progresses under the influence of temperature, humidity, and light! Example of impurity analysis in ethanol and acetone.

This is an example of analyzing impurities detected in a solvent when stored in inappropriate conditions. Ethanol, which was 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. [Impurity Analysis in Ethanol] - 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 (the wash bottle was not sealed as the opening was exposed). - Result: Impurities such as triethyl borate and alkylbenzenes were detected. *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.

We will introduce examples of comparing the components of color developers contained in thermal paper using solvent extraction!

As a pre-treatment for GC-MS analysis, solvent extraction can sometimes allow for highly sensitive analysis of target substances. This document introduces examples of component comparison of dirt wiped with a cloth and component comparison of color developers contained in thermal paper using solvent extraction. In addition to solvent extraction, we can propose suitable methods from various pre-treatment techniques tailored to your samples and analysis targets, so please feel free to contact us.

The Fukuoka area, along with the rest of Kyushu, faces serious risks of flooding and typhoons almost every year. In particular, August 2025 left significant flooding and landslide damage across various regions due to consecutive linear precipitation bands and Typhoon No. 12. When such unpredictable disasters occur, the loss of lifelines such as electricity can lead to catastrophic damage. To protect households and businesses from unforeseen circumstances, it is essential to prepare power sources as part of "Fukuoka Power Outage Measures." An effective solution is a system that can provide stable electricity even during disasters. Introducing storage batteries for disaster preparedness in Fukuoka is not only crucial for ensuring a safe living environment for households but also essential for business continuity planning (BCP measures using storage batteries) to keep corporate activities running. Securing emergency power sources at bases in Fukuoka for offices and factories is extremely important for business continuity. Shall we start preparing for disasters that can happen at any time? For inquiries about optimal capacity, installation space, and implementation costs, please feel free to contact our Fukuoka sales office. Our specialized staff will propose the best plan tailored to your needs.
