Charge-transfer Devices in Chemical Analysis

This work describes the benefits of using the charge-transfer device (CTD), a type of solid-state multichannel detector, as it is used for chemical imaging and analysis. Numerous complete spectroscopy systems now include charge-transfer devices. The work highlights the potential uses of CTDs, which essentially allow chemists to get more out of their instruments and avoid false positive, or false negative, results. CTDs could be the future way in all kinds of spectroscopic instrumentation, including Raman, atomic emission and luminescence spectroscopy, atomic source diagnostics and planar chromatography.
