“…A somewhat novel approach to designing a chromatographic detector employs a light source to illuminate a flow cell from which the emergent light is directed to a concave mirror which reflects the light at different angles according to wavelength (353). The modification of a Beckman DB series spectrophotometer as a dual-beam liquid chromatographic detector has been described (215). Multiwavelength detectors include one which is designed to scan from 200 to 800 nm in 375 ms (501) and another instrument which is dual-beam and utilizes 256 linear photodiode array detectors for scanning from 200 to 800 nm (411,412).…”
