Benchtop Spectrometer.

Using a solid state charge coupled device (CCD) instead of conventional photomultiplier detectors, the Assure desktop spectrometer provides many of the analytical operations of larger laboratory units with greater flexibility and lower cost. The small size of the CCD chip enables the optical system to be reduced in size and the overall spectrometer to be desktop-mounted. Since a single chip has the equivalent of 8000 detectors, all the wavelengths necessary for multi-element, multi-base analysis are available and additional calibrations can be added or extended in the field without the need for additional hardware. The use of CCD detection also enables complete spectrum scans to be recorded. This provides an electronic photograph that can be stored for future reference or used for comparison with other scans for identification and semi-quantitative analysis of unknown or unexpected elements. Data processing is undertaken by a built-in Pentium compatible processor and the software provides for automatic profil ing and simultaneous background correction on every measurement.
