Multidimensional Vibrational Circular Dichroism Apparatus Equipped with Quantum Cascade Laser for liquid sample analysis

February 8, 2022

The multidimensional vibrational Circular Dichroism spectrometer, which was developed in collaboration* with a research group led by Professor Hisako Sato of Ehime University, is a conventional vibration circular dichroism spectrometer with a quantum cascade laser. It is a complex type multifunctional system that combines cascade laser, spectroscopic scanning technology, and automatic stage.
This system can measure vibrational circular dichroism with
high speed and high sensitivity  based on monochromaticity and high brightness advantages of quantum cascade lasers.

Since it is a concurrent system that can switch between thermal light source of conventional FT / IR and quantum cascade laser, it is possible to measure in both regions as wide wavenumber region (4000-750 cm-1) using a thermal light source, and wave number scanning and fixed wavenumber measurement in a limited wavenumber region (1740-1500 cm-1) using a cascade laser.

In particular, measurement can be done in a second as minimum under fixed wavenumber condition, and the spatial distribution and time resolve reaction of chiral biological samples can be detected using a measurement technique of scanning space made possible by the addition of microscopic scanning technology and automatic stage.

For futher details,  please refer the JASCO Report.

* The development of this system is supported from Professor Hisako Sato (JPMJMI18GC) in the research and development project “Development of multidimensional vibrational circular dichroism spectroscopy” in the area of ​​the future society creation project in Japan Science and Technology Agency (JST MIRAI).
