Analysis of mica sheet adhesive components using GC/MS.

It is possible to investigate components that cannot be identified by spectroscopy alone, as well as trace additives that cannot be detected!

We will introduce the analysis of the components of mica sheet adhesive using GC/MS. To investigate what components are contained in the mica sheet, spectroscopic measurements were conducted, suggesting the use of silicone-based adhesives. To examine the composition of the silicone-based adhesive used, GC/MS measurements were performed. It was found that pentacyclooctasiloxane is used, and it was also discovered that plasticizers such as dibutyl phthalate and chain-saturated hydrocarbons like tridecane are added as lubricants. [Mica Sheet Components] ■ Pentacyclooctasiloxane (cage-like polymethylsilsesquioxane) ■ Dibutyl phthalate ■ Chain-saturated hydrocarbons such as tridecane *For more details, please refer to the PDF document or feel free to contact us.

Comparison of components in liquid crystal panels using gas chromatography-mass spectrometry (GC-MS) is published!

This document introduces a comparison of components in PC monitors and digital clocks using gas chromatography-mass spectrometry (GC-MS). Liquid crystal displays contain small organic substances (liquid crystal molecules). These have evolved into molecular structures suitable for product characteristics due to technological innovations. Our company clarifies these differences at the molecular level using GC-MS, allowing us to confirm that the liquid crystal molecules are appropriate for their intended use and to check for the presence of impurities.

Focusing on sandalwood (byakudan), which is used as a raw material for incense! Here is an example of component analysis using GC-MS.

Due to the risk of depletion of natural ingredients, artificially synthesized alternative components may be used, and their identification is suitable through separation and analysis methods such as GCMS. This time, we focused on sandalwood (Byakudan), which is used as a raw material for incense. We tested whether the components of sandalwood could be detected in two types of incense (A and B) with sandalwood scent. In incense A, santanol was detected, whereas in incense B, santanol was not detected, and another aromatic component was found. Among these, bugdanol is a type of synthetic fragrance, and due to its structural characteristics, it is believed to have a sandalwood-like scent. [Components of Incense A] ■ Bugdanol: Trace amount ■ Cedrol: None ■ α-Santalol: Present ■ β-Santalol: Present *For more details, please refer to the PDF document or feel free to contact us.

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.*

It is possible to analyze with high sensitivity using thermal desorption GC-MS analysis! We propose methods tailored to the symptoms of malfunctions and your objectives.

Various additives are used in polymers to improve stability and processability; however, due to environmental impact and long-term storage, additive components may precipitate on the polymer surface, or the additives themselves may undergo chemical changes, leading to discoloration and degradation. This document presents examples of analyses conducted using thermal desorption GC-MS to examine the bleed-out of additives and the chemical changes of additive components due to UV irradiation. Although additive components are present in small quantities compared to the main polymer components, they can be analyzed sensitively using thermal desorption GC-MS. We propose methods tailored to specific issues or objectives, such as predicting product degradation in combination with reliability testing, thermal analysis, and main component analysis, so please 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.

We are pleased to announce the development of the vehicle passage time prediction system "MS-VPP," which measures the speed of vehicles approaching construction sites using microwave sensors and informs the predicted passage time through signage and tablets. This system will be available to construction contractors starting in November 2025. ■Product Overview - "MS-VPP" detects vehicles approaching construction sites and measures their speed using microwave sensors, displaying the vehicle speed and the predicted passage time at specified locations on signage and tablets. It can also measure and display data for vehicles passing continuously. - The data control panel connected to the microwave sensor transmits the vehicle speed data and calculated passage prediction time via LTE. By utilizing microwave sensors, it enables accurate detection and speed measurement of vehicles even at night or in bad weather, and since data processing occurs on the receiving side without going through the cloud, information can be displayed without any time lag. - As a result, drivers of construction vehicles exiting from construction entrances and workers directing traffic can understand "how many seconds until a vehicle passes near the site entrance," thereby implementing safety measures in areas with poor visibility.
