Vibrational Circular Dichroism
An essential tool for absolute configuration of molecules.
JASCO has developed the FVS-6000 high performance VCD (Vibrational Circular Dichroism) spectrometer and VFT-4000 Vibrational Circular Dichroism (VCD) attachment with the most advanced DSP electronics and auto-alignment mechanisms.
The FVS-6000 not only allows you to easily obtain fingerprint VCD spectra, but also has several unique features such as a measurement range extension option of 4000-750 cm-1.
Since the CD signals in the infrared region are one or more orders of magnitude lower than ECD signals in the UV-Vis region, high sensitivity and stability are required for a VCD spectrometer.
The FVS-6000 is the VCD spectrometer of choice for highly sensitive VCD measurements.
The VFT-4000 is a VCD attachment for the FT/IR-4000/6000 FT-IR spectrometers, developed for measuring vibrational circular dichroism in the infrared region. The VFT-4000 can be used to obtain very useful information for the optical activity of carbohydrates and provide tertiary structure identification of chiral molecules.
The VFT-4000 can cover a wide spectral range (4000-750 cm-1), enabling measurement of OH and NH bands. Detectors can be easily exchanged with no manual alignment, and optical filters can be switched by a PC-controlled 6-position filter wheel.
A unique, single platform software package for any JASCO spectroscopy system
JASCO is the first manufacturer to develop a powerful, cross-platform software package, “Spectra Manager”, for controlling a wide range of spectroscopic instrumentation.
Spectra Manager II software offers quick and easy VCD data acquisition and analysis. Theoretically calculated VCD intensities from a commercially available calculation software can be plotted as simulated spectra to be compared with the experimental data for further tertiary structure analysis of molecules.
