Using fragrance as a keyword, we analyzed common incense and compared the characteristics of its molecular structure with other materials. The three representative fragrant woods obtained from trees are sandalwood, agarwood, and kyara, but this time we collected data on incense and sandalwood. With aldehyde groups and aliphatic cyclic structures as features, it is speculated that the woody scent is mainly due to the aliphatic cyclic structure. [Analysis Overview] ■ Analysis Samples: Incense, Sandalwood ■ Identification of fragrance components by thermal desorption GC-MS (180°C) - Confirmed peaks with the same detection time as sandalwood - Indicates that sandalwood is used as a fragrance in the incense *For more details, please refer to the PDF document or feel free to contact us.

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.

Blue light cut film has the effect of suppressing the transmission of visible light, particularly light with a wavelength of 500nm or less, compared to regular PET film. Using a spectrophotometer, we examined how the light transmission of the blue light cut film changes under UV irradiation.

Additionally, we conducted an analysis of the reactions occurring within the film using GC-MS.

We will introduce a case where ICP measurement was conducted using panels before and after reliability testing, along with quantification. The liquid crystal molecules in an LCD are oriented within the panel, and the display is controlled by changes in the orientation state of the liquid crystal due to voltage. When ionic substances, such as metal elements, are present inside the panel, the liquid crystal does not operate correctly, leading to display defects. Ionic substances are known to increase due to contamination during manufacturing or long-term use, making it important to quantify and understand them as part of panel quality. Metal ions can be quantitatively analyzed using ICP analysis, and depending on the differences in pretreatment methods and detection sensitivity, ICP-AES and ICP-MS are used selectively.

Shape memory alloys are alloys that have the property of returning to their original shape when heated above a specific temperature, even after being deformed. The manifestation of shape memory is due to a phase transformation (martensitic transformation). By capturing the thermal energy changes during the transformation using Differential Scanning Calorimetry (DSC), we measured the transformation temperatures of three types of shape memory alloy products and investigated their relationship with composition through elemental analysis. When a deformed wire is immersed in hot water, it instantly returns to its original shape. 【Transformation Temperature Measurement by DSC】 - Investigated the transformation temperatures of three types of shape memory alloys using DSC. - It was found that the transformation temperatures are in the order of A > B > C. - Shape memory alloy C is believed to be in a superelastic state at room temperature. - Af: A 45.91, B 41.20, C 11.83 - Ms: A 43.75, B 36.25, C -15.59 *For more details, please refer to the PDF document or feel free to contact us.

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.

This document introduces a pretreatment method to enable the analysis of substances that are difficult to analyze using GC/MS. The pretreatment that converts difficult-to-analyze substances into analyzable substances is called "derivatization." Methods such as esterification, acylation, and silylation are used selectively according to the type and characteristics of the difficult-to-analyze substances. GC/MS measurements were conducted on citric acid solutions and citric acid solutions after esterification. It was found that citric acid, being a carboxylic acid, could not be effectively detected without derivatization, but after esterification, trimethyl citrate was detected, confirming the presence of citric acid. By performing appropriate derivatization, more accurate analysis becomes possible.
