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.

Contec Co., Ltd. has started selling the "SH-9210TSN," an industrial managed switching hub that has obtained CC-Link IE TSN recommended network wiring component certification Class B. It features dual power supply redundancy, a DC power input, eight gigabit ports, and two SFP slots. The SH-9210TSN complies with IEEE 802.3ab (1000BASE-T), IEEE 802.3u (100BASE-TX), and IEEE 802.3 (10BASE-T) standards, and is designed for use in environments where quiet operation and long lifespan are required due to its fanless design. Additionally, it achieves an operating temperature range of -10 to 65°C thanks to its excellent heat dissipation metal casing. It can be installed on a 35mm DIN rail or mounted on walls using various mounting brackets. In addition to a wide-range DC power input (12-48VDC), it supports input from two power supply lines and includes various managed functions for network management, control, and reliability enhancement.

The "Mechanical Stitching 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 on 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.
