Spectrophotometer UV-Visible-NIR Spectroscopy
WebAll spectrophotometers contain four elements: 1. A source of radiation. 2. An optical system, or monochromator, to isolate a narrow band of wavelengths from the whole spectrum emitted by the source. 3. The sample (and its cell if it is liquid or gaseous). 4. A detector of radiation and its auxiliary equipment. WebJun 30, 2024 · Since this spectroscopy technique relies on the use of light, let’s first consider the properties of light.
