  • Lesson 6: Detectors for HPLC

    These detectors are most commonly used for steady-state measurements, but in certain cases, when coupled to a fast amplifier, may also be used for time-resolved measurements. When two detectors cover a similar wavelength range, such as InGaAs and Ge, the choice is based on gain, noise factors and response at a specific wavelength of interest.

    2021-5-30 · For photon counting, detectors with intrinsic gain are necessary. A commonly used detector is a photomultiplier tube, which uses dynodes to provide intrinsic gain to the detector. Photodiodes do not have intrinsic gain which means 1 incident photon will, at most, allow the flow of 1 electron, which is too small of a signal to overcome the noise.

    The design for this filter is a rejection band that attenuates 280-nm light in transmission. When used in a reflective configuration with a light-absorbing mount, it acts as a bandpass filter. The blocking can be increased by increasing the number of bounces in the system. Keeping the angle of incidence low (<~25°) minimizes polarization effects.
