Abstract : This is the second article in a two part series describing the operation, performance characteristics, and spectroscopic application of Charge Transfer Devices (CTDs) in analytical chemistry. The first article in the series describes the new generation of integrating multichannel detectors, the charge also discusses the spectroscopically pertinent characteristics of these detectors and presents performance data for representative devices. This article covers three major topics related to the optimum use of integrating detectors in analytical spectroscopy. The advantages of employing integrating multichannel detectors in analytical spectroscopy rather than a single detector in a wavelength scanning system or an interferometer are discussed. Included are detector read noise considerations which have not been considered in previous performance comparisons. Keywords: Charge transfer devices, Charge coupled device, Charge injection device, Multichannel emission spectroscopy, Multichannel luminescence spectroscopy, Multichannel absorption spectroscopy.
