    Spectrophotometers

    Spectrophotometers For Single & Multi Element Analysis
    The Optical Emission Spectrometer is specially built to provide rapid, precise, accurate and certifiable elemental analysis in weight percentages of metals. The spectrometer features ruggedness, reliability and accuracy.
    In Optical Emission Spectrometer all elements in a sample emit light simultaneously when the sample is subjected to a high voltage using a silver or tungsten counter-electrode. Since there are many elements in a metal alloy, the emitted light appears as white light. Each element has its own set of characteristic wavelengths and when this white light is focused on a holographic grating [the latest in optical technology] the white light is diffracted [broken] into its component wavelengths, which are in turn focused on a microchip consisting of 3648 light sensitive diodes, known as a CCD or Charge Coupled Device. Based on the well-known concept that the intensity of light is proportional to the concentration of the corresponding element, analytical curves are generated by running Certified Reference Materials, also known as Primary Standards. These curves [one for each element] are stored in a Computer`s memory. When an unknown metal sample is run, the software takes over and referring the respective intensities to the curves stored in the memory, gives the elemental concentrations as direct weight percentages.

    Salient features of Optical Emission Spectrometer are:

    Hardware:

    • Arc-spark emission
    • compact, with high stability
    • CCD Detectors
    • fully automatic, up controlled
