Image, charge couple device

Jackson, P., The use of polyacrylamide-gel electrophoresis for the high-reso-lution separation of reducing saccharides labeled with the fluorophore 8-ami-nonaphthalene-l,3,6-trisulfonic acid. Detection of picomolar quantities by an imaging system based on a cooled charge-coupled device, Biochem. ]., 270, 705, 1990. [Pg.426]

The main detectors used in AES today are photomultiplier tubes (PMTs), photodiode arrays (PDAs), charge-coupled devices (CCDs), and vidicons, image dissectors, and charge-injection detectors (CIDs). An innovative CCD detector for AES has been described [147]. New developments are the array detector AES. With modem multichannel echelle spectral analysers it is possible to analyse any luminous event (flash, spark, laser-induced plasma, discharge) instantly. Considering the complexity of emission spectra, the importance of spectral resolution cannot be overemphasised. Table 8.25 shows some typical spectral emission lines of some common elements. Atomic plasma emission sources can act as chromatographic detectors, e.g. GC-AED (see Chapter 4). [Pg.614]

Because of the double exposure, the preparation suffers from increased bleaching and photodamage. Furthermore, split-imaging on charge-coupled-device (CCD) systems (see Textbox 1) is not an option. Nevertheless, excitation ratioing may be an economic choice for laboratories that have an old Fura-imaging setup. These microscopes often allow very fast excitation switching... [Pg.307]

Figure 4.2 Schematic diagram of a charge-coupled device (CCD) imaging sensor. It consists of a semiconducting substrate (silicon), topped by a conducting material (doped polysilicon), separated by an insulating layer of silicon dioxide. By applying charge to the polysilicon electrodes, a localized potential well is formed, which traps the charge created by the incident light as it enters the silicon substrate.
