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 at construction sites around the world. This time, we would like to introduce the construction site 'Rotterdam Capacity Growth (RDCG)' in Rotterdam, Netherlands. PERI is supporting the expansion of one of Europe's largest biofuel refineries by providing innovative scaffolding solutions. This helps meet Europe's high safety standards, achieve efficient processes, and significantly contribute to the decarbonization of air transport. As part of the Rotterdam Capacity Growth (RDCG) project, one of Europe's largest biofuel refineries is under construction. This will increase the annual production capacity of biofuels from 1.4 million tons to 2.7 million tons. PERI products: 1. PERI UP (modular scaffolding) PERI Japan Co., Ltd.

In preparation for this summer's extreme heat, we have completed a "Heatwave Countermeasure Catalog" that will help improve the working environment in the manufacturing and logistics industries. The catalog includes a wide range of products for facility improvements, such as fireproof certified heat-shielding sheets that cut radiant heat by 97%, heat-shielding curtains, roof and window countermeasure products, and fans suitable for large spaces, as well as black globe thermometers that can measure WBGT, wearable alert bands, mobile cooling shelters, and fan-equipped work clothing. We have consolidated measures for "building countermeasures," "work space countermeasures," and "personal countermeasures" into one volume. It can also be used as reference material for discussions in safety and health committees. Please take a look at the specific measures that simultaneously achieve heat countermeasures and energy conservation/CO₂ reduction.

We are pleased to announce the establishment of the "Kyushu Sales Office" aimed at strengthening our business foundation in the Kyushu area. With the opening of the new sales office, we will be able to respond more quickly and flexibly to our customers in the Kyushu region, while enhancing our support system closely tied to the local community.

We have recently started a demonstration experiment aimed at addressing antibiotic-resistant bacteria in dairy farming. Utilizing compost environments, we will examine the impact of using our technology-based aqueous solutions on microbial dynamics. This experiment is being conducted with field cooperation, aiming to establish a new approach that contributes to the realization of a sustainable livestock environment and the reduction of antibiotic usage. In this trial, we will set up a spray group (Group H) and a non-spray group (Group C), and will conduct a time-series comparison before spraying, immediately after spraying, and at 1, 3, 7, 14, 28, and 42 days, as well as at the maturation stage. We will perform sampling from the upper, middle, and lower layers of the compost at a depth of 10 cm, while simultaneously collecting temperature logs (external temperature and two internal compost temperatures) to analyze microbial changes and fermentation status from multiple angles. Based on scientific data, we will pursue a balance between safety and effectiveness, and work towards contributing to the livestock industry.
