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!

This is an introduction to the analysis of the components of mica sheet adhesives using GC/MS. To investigate what components are contained in the mica sheet, spectroscopic measurements were conducted, suggesting that silicone-based adhesives are used. To examine the composition of the silicone-based adhesive, GC/MS measurements were performed. It was found that pentacyclooctasiloxane is used, and it was also discovered that dibutyl phthalate is added as a plasticizer and chain-saturated hydrocarbons such as tridecane are added as lubricants. 【Components of the mica sheet】 ■ 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. [Contents] ■ Component comparison of PC monitors and digital clocks using GC-MS ■ Case studies of GC-MS analysis of liquid crystal components We compared the number of components and characteristics of segment-type liquid crystal displays (digital clocks) and color TFT liquid crystal displays (PC monitors). *For more details, please refer to the PDF document or feel free to contact us.

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 for separation and analysis using 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 its fragrance. In incense A, santanol was detected, while in incense B, santanol was not detected, and another fragrant 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 amounts ■ 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 confirmed from a solvent when high-purity products are stored in inappropriate environments, using liquid injection GC-MS. 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. 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 opening of the wash bottle was not sealed). ■ 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 good sensitivity using thermal desorption GC-MS analysis! We propose methods tailored to the symptoms of issues and 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 analyzing the bleed-out of additives and the chemical changes of additive components due to UV irradiation using thermal desorption GC-MS. Although additive components are present in only small amounts 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.

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; however, analyzing components that do not volatilize upon heating or those with low detection sensitivity is challenging. 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 difficult. However, by performing reactive thermal decomposition GCMS, it is possible to detect the methyl esters of monomers and to separate and analyze them from the additives. Thus, even when the target analytes are difficult to detect using conventional analysis, reactive thermal decomposition GCMS allows for sensitive detection by selecting appropriate reagents for the analytes.
