Solid Sample Analysis Application Notes

 
   
 
    The DC Arc technique has been relied upon for decades as a tool for the direct analysis of a wide range of solid materials. The earliest systems, many of which are still in use today, were photographic plate spectrographs. These systems offered the advantage of providing a permanent photographic record a sample?s spectrum, but also carried with it the cumbersome need to view and interpret photographic plates. These early generation instruments were replaced, first by PMT?based simultaneous spectrometers and then CID based DC Arc spectrometers, each with their own strengths and weaknesses.

The Prodigy DC Arc is state-of-the-art DC Arc spectrometer that offers many advantages over all of its predecessors.

   
   

The Prodigy DC Arc stand is a significant improvement over the original "Spex" stand that was used in earlier DC Arc instruments. This user-friendly new arc stand incorporates a counter electrode that simply rotates out of the way to facilitate installation of new sample electrodes and then rotates back into position for the next sample.

This new arc stand also features a current-stabilized power supply for enhanced stability. A Stallwood Jet is available for reduction of CN band emission when needed.

 
  Why choose DC Arc for Elemental Analysis?
For a few simple reasons, DC Arc is revered by those who use it. The reasons include:
 
  The Echelle Optical System
The polychromator used in Prodigy DC Arc is the same long focal-length Echelle spectrometer used in the Prodigy ICP product line. This spectrometer provides the DC Arc user with analytical capabilities which have never before been available to this community. Capabilities such as:
   
    Speed of analysis
  • Measure all elements in 1 burn in under 60 seconds
  • Full wavelength coverage with no interorder overlaps
  • Measure wavelengths from 175 nm to 900 nm
    Fewer spectral interferences
  • State-of-the-art L-PAD detection system is 4 times larger than earlier detectors eliminating interorder overlap
    True simultaneous integration for every wavelength
  • Simultaneous background correction
  • Superior internal standardization capability
  • Analytical line averaging capability for superior accuracy
  • Simultaneous measurement of strong and weak emission lines with no need to alter resolution
  • Availability of a user selectable resolution option
