NMR analysis of liquid crystal compounds

Introducing the information obtained from NMR, using 1H NMR, 13C NMR, and DEPT measurements as examples!

At Aites Co., Ltd., we conduct "NMR analysis of liquid crystal compounds." NMR is an analytical method that reveals the connections between atoms that make up a molecule, and it is used alongside mass spectrometry and infrared spectroscopy for determining the structure of compounds. In the downloadable materials, we introduce information obtained from NMR using 4-butoxy-4'-cyanobiphenyl (CAS number 52709-87-2) as an example, including 1H NMR, 13C NMR, and DEPT measurements. Please feel free to download and take a look. [Measurement Examples] ■ 1H NMR measurement ■ 13C NMR measurement and DEPT measurement ■ Other NMR measurement techniques *For more details, please download the PDF or feel free to contact us.

Distinguish and identify compounds with similar structures! You can obtain information such as the number of protons and structural characteristics.

At Aites Co., Ltd., we conduct 1H NMR analysis of phthalate esters. NMR analysis and GCMS analysis are effective for distinguishing and identifying compounds with similar structures. In this analysis, we can obtain information about the number of protons from the integral values, structural features such as functional groups from the chemical shifts, and the positional relationships with surrounding protons from the coupling patterns and coupling constants. *For more details, please refer to the PDF document or feel free to contact us.

Rich equipment and expertise! We will elucidate the molecular structures of materials in general through chemical instrument analysis!

There are various types of liquid crystal materials, including low molecular weight compounds used in LCD panels and high molecular weight polymers used in printed circuit boards and electronic components. We would like to introduce examples of molecular structure analysis of these low molecular weight liquid crystals and high molecular weight liquid crystals (LCP). Our company, equipped with a wealth of devices and expertise, can handle reliability testing and analytical analysis of not only liquid crystal materials but also various other materials. Please feel free to consult us regarding the understanding of molecular structures of imported overseas products and materials, as well as troubleshooting issues. 【Case Study Details】 ■ Molecular structure analysis using FT-IR ■ Understanding of surface functional groups (molecular groups) through XPS (ESCA) analysis ■ Example of LCD liquid crystal material analysis using GC-MS *For more details, please refer to the PDF document or feel free to contact us.

We propose analytical methods tailored to materials and purposes! Here are examples of chemical analysis for each component, such as liquid crystals and sealing materials.

Liquid crystal displays use various organic materials, including liquid crystals, sealing materials, encapsulants, and polarizers. Considering the material properties and degradation mechanisms of each component from a chemical perspective is important for product evaluation and defect analysis. This document presents examples of chemical analysis for the components of liquid crystal displays. [Examples of Chemical Analysis] ■FT-IR: Principal component analysis ■EDX: Elemental analysis ■GCMS: Liquid crystal component analysis ■HS-GCMS: Outgassing analysis (degradation analysis) and more *For more details, please refer to the PDF document or feel free to contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling and tripping of wired cables × Cable disconnection or damage × Worry about forgetting to turn on the switch after temporarily stopping the sensor. × Want to be notified of bed exit even from a location away from the nurse call outlet. Such concerns can be resolved simply by connecting to a wireless set linked to the nurse call system! Our nurse call linked wireless set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed, alleviating concerns about tripping and falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations away from the nurse call outlet, allowing for more flexible equipment placement.
