A typical UV detector permits to pick out the wavelength concerning 190nm and 400 nm. In contrast to your UV detector, a visual (VIS) detector employs for a longer time wavelengths, for example 400nm to 800 nm.When NO2* decays to its floor point out, a photon is released, that may be detected by a photometer. The signal is proportional on the nitro
