Circular Dichroism Spectropolarimeter
Technical and Characterization Specifications:
- Determines the optical purity of chiral molecules
- Measures the left-and right-handed circularly polarized light of optically active molecules.
- Measures the chiroptical properties of solutions (chiral solutes, viz., peptides and proteins, dissolved in solvent)
- Determines the chiroptical behaviour of chiral liquid crystal samples (as a function of temperature)
- Determines the binding constants
- Useful in determining kinetics of folding and unfolding of macromolecules
- Provides thermodynamic parameters from temperature dependencies of CD signals
- Equipped with Mettler FP90 hot stage
- Comprises a variable wavelength polarimeter and absorption spectrophotometer (163-900 nm)
- Up to four channels can be acquired simultaneously; the internal signals are selected from CD, FDCD, ORD, LD UV and Fluorescence
- The acquired data are controlled by Jasco’s spectra manager
