  • Circular dichroism detector for HPLC
    Patent number: 6118536
    Abstract: A circular dichroism detector includes a light source having a large emission intensity in the ultraviolet region such as an HgXe lamp or Hg lamp, a diffraction grating for wavelength dispersing the light emitted from the light source, a polarizer for linearly polarizing the light emitted from the light source, a PEM for modulating wavelength dispersed linearly polarized light to alternately produce left-handed circularly polarized light and right-handed circularly polarized light, a flow cell through which the circularly polarized light will be passed, and a photodiode for detecting the circularly polarized light passing through the flow cell.
