Circular Dichroism
The Aviv Circular Dichroism Spectrometer, model 215, records CD as a function of wavelength, time, temperature, pH and concentration using a double monochromator containing two UV grade prisms as dispersing elements. Right and left circularly polarized light is produced by a 50 KHz photoelastic modulator.
The instrument includes Windows environment software by AVIV for instrument control, processing and data acquisition.
