In forward optic spectrophotometers, electromagnetic radiation of a specified wavelength is passed through sample solutions. Because radiation from source is polychromatic (consists of light of all wavelengths), the various wavelengths of radiation must be separated... [Pg.3462]

Forward optic spectrophotometers are either singlebeam or double-beam spectrophotometers. The singlebeam instruments can be either very simple or expensive depending on the sophistication desired or needed. Simple single-beam instruments have poor stability and excessive drift. These advantages are eliminated in systems equipped with a high-resolution monochromator with adjustable slits, controlled by microprocessors for rapid data acquisition and evaluation of data. [Pg.3465]
