  • What are Evaporative Light-Scattering Detectors?

    2019-12-10 · Evaporative Light-Scattering Detectors. ELSDs are aerosol-based HPLC detectors which work by converting the eluents of target components (carried by an inert carrier gas such as Nitrogen) to a fine spray via a nebulizer. This spray is then heated so that only the mobile phase evaporates. Light is then focused on the remaining target substance and scattered light is detected.

    2021-7-24 · The lower chopping frequency depends on the 1/f noise of the detector itself, while the higher chopping frequency is limited by the response speed of the detector. So we recommend using a chopping frequency in the flat region unless a specific problem arises. The chopping frequency we use for testing InSb photoconductive detectors is 1200 Hz.

  • What is a CCD Detector? - HORIBA

    A CCD or Charge Coupled Device is a highly sensitive photon detector. It is divided up into a large number of light-sensitive small areas known as pixels, which can be used to assemble an image of the area of interest. A CCD is a silicon-based multi-channel array detector of UV, visible and near-infra light.
