Jasco VFT-4000 Vibrational Circular Dichroism attachment

Accessory for enhancing function of FT/IR-4000/6000 series

The VFT-4000 is a VCD attachment for the FT/IR-4000/6000 spectrometers developed for measuring vibrational circular dichroism in the infrared region. The VFT-4000 allows to obtain very useful information for optical activity of carbohydrates which do not have any absorption in UV-Vis region and tertiary structure identification of molecules. Since the CD signals in the infrared region are one or more order magnitude lower than ECD signals in the UV-Vis region, the VCD spectrometer needs high sensitivity and high stability. The VFT-4000 enables highly stable and sensitive measurement by Lock-in detection by DSP with sophisticated algorism optimized to VCD and the thermal control of the PEM.

The VFT-4000 can be easily installed into the FT/IR-4000/6000 in the field without any complicated adjustments.
