How does a photodiode array work?
Photodiode array (PDA) detectors record light absorption at different wavelengths and can provide spectra of the analytes. This is useful in identifying unknowns. Mass spectrometry (MS) is a better detector for unknowns.
How a photodiode array is used to measure absorbance?
The light that passes through the flow cell enters the photodetector (photodiode) and is converted into an electrical signal corresponding to the intensity of the light, which is processed as absorbance.
What is photodiode array detection?
A Photodiode Array Detector is a microprocessor controlled multi-channel detector that permits simultaneous access to spectral data for several wavelengths simultaneously. In comparison the conventional UV-Visible detector has only a single channel detector.
What are diode arrays used for?
Diode arrays have been used for many years in both digital and linear circuits. Diode arrays are commonly used in such applications as computer and peripheral I/O ports, core driver switching, high frequency data lines, interface networks, LAN and WAN networks, and steering diode applications.
