Читать книгу Continuous Emission Monitoring - James A. Jahnke - Страница 140

Prisms disperse ultraviolet, visible, and infrared radiation due to differences in the wavelength‐dependent index of refraction in the prism material. Prism spectrometers are available in the UV and visible spectral regions; although they have been used in atomic absorption spectrometers for measuring metals, they are not typically used in pollutant gas monitoring applications.
