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.*

We conduct surface analysis, foreign substance analysis, and organic composition analysis.

At AITES, we propose and conduct contract analysis menus suitable for the purpose and sample, including the analysis of organic and inorganic substances, foreign matter, and surface analysis. In this department, we perform component analysis of micro foreign substances using advanced sampling techniques, as well as impurity analysis in samples, conducting both qualitative and quantitative analysis of organic and inorganic components. Additionally, we analyze the surface of samples for contamination and oxidation states. 【Service List】 ■ Component analysis of epoxy resin hardeners using Pyrolysis GC/MS ■ Analysis of micro organic foreign substances using Imaging FT-IR ■ Analysis of micro foreign substances using Micro Raman Spectroscopy ■ Ion Chromatography (IC) analysis, etc. *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.

PERI products are used on construction sites around the world. This time, we would like to introduce the "Tassonaro Railway Bridge Renovation Project" in Italy. This historic railway bridge, spanning the Tassonaro River, underwent extensive renovation work in 2023. The reason for the renovation was the cracking of the concrete due to ground subsidence. Built in the 1930s with stone and white marble, this railway bridge is approximately 200 meters long and consists of nine arches. It survived both bombing and sabotage during World War II. To protect the bridge from seismic activity caused by the clay embankment, deep foundations were excavated down to 35 meters below the river surface during construction. Structural renovations were carried out inside the nine arches of the railway bridge using concrete and rebar. To ensure the partial preservation of the structure, PERI developed a custom special solution that combined multiple products and provided support for both the planning phase and on-site construction. PERI products: 1. VARIO GT24 (wall formwork) 2. RUNDFLEX (circular wall formwork) 3. PERI UP (modular scaffolding system) PERI Japan Co., Ltd.

"Civil Engineering Watching - Infrastructure Encyclopedia: Collection of Civil Engineering Structures" is a portal site for images and information about civil engineering structures that form social infrastructure facilities. We have recently published photos and articles about the "Saale Valley Bridge." The "Saale Valley Bridge" was constructed at the border between Saxony-Anhalt and Thuringia, in Bad Kösen, Naumburg. Boasting an impressive height of up to 60 meters, this structure spans a total length of 1.2 kilometers and a width of 12.5 meters, harmoniously blending with the surrounding landscape designated as a nature reserve. In addition to the "Saale Valley Bridge," various civil engineering projects, photos, and articles related to civil engineering are also featured, so we hope you will take a look.
