The Charge Coupled Device (CCD) technology, which is similar to that used in digital cameras, phones and video recorders, enables a single, small, yet robust instrument to measure the whole spectrum necessary for the analysis of all the common metal bases. In fact the most appropriate analytical or spectral ‘lines’ can be chosen by software rather than hardware such that Metalscan spectrometers are not limited in the number of elements that can be analysed. For example a typical conventional spectrometer incorporating Photo Multiplier Tube (PMT) detectors might have about 30 analytical channels fixed by expensive hardware, while a CCD based unit would have access to over 1000 channels, all selectable by software. The CCD provides an electronic slit plate where electronics can be used to search for line peaks and counteract any thermal or mechanical shifts, which are often the source of problems with conventional units.
