Phototube Detector in Spectrophotometry by alvinbb is a document available to read on EtoBox.
A spectrophotometer is an instrument used to detect the amount of light absorbed by molecules. It consists of five main components: a light source, prism or diffraction grating, aperture or slit, detector such as a phototube, and a digital meter. Light is split into its wavelengths by the grating and passes through a slit to the phototube. A sample in a cuvette absorbs some light while the rest is transmitted to the detector, which converts the radiant energy into an electrical signal displayed in useful un
