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.

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.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher.

This time, we will explain the differences in roles between the "accounting system" and the "document management system," which are surprisingly not well known, as well as points that are often overlooked in legal compliance. ■ The difference between accounting systems and document management systems is their "scope of coverage." - Accounting System = Management of "money (numbers)" - Document Management System = Management of "evidence (documents)" ■ Documents that are often overlooked in accounting systems The accounting system primarily focuses on "accounting processes." - "Estimates" where no money movement occurs - "Delivery notes" and "purchase orders," which are intermediate points in transactions ⇒ There are cases where these are not saved or managed in the accounting system. This could be considered a deficiency under the Electronic Bookkeeping Act. ■ Supplementing the missing parts with an "independent system" While there are high-function ERP (Enterprise Resource Planning) systems that can manage everything from estimates to invoicing seamlessly, the reality is that the cost can be a significant barrier to implementation. Therefore, there is also the option of managing documents with an independent document management system like paperlogic. Paperlogic is currently offering a free trial. Please feel free to contact us.
