Diode array detector
Definition: A piece of apparatus, consisting of a two-dimensional pattern of diodes and a prism, that is used to detect organic compounds. As the sample passes through a cell or cuvette it is illuminated with light in the region 190--1100 nm and any light transmitted through the sample is dispersed by the prism, so that light of different wavelengths falls on different diodes. The output from the array is used to construct an absorption spectrum that can be compared with standard spectra for identification purposes. Alternatively, a single diode can be used to monitor a specific wavelength at which there is maximum absorption.
