​​Prodigy and the DC Arc Technique

Fast, quantitative, elemental analyses of difficult samples are hallmarks of the DC Arc approach. Few other techniques can challenge the ease-of-use or productivity of DC Arc when it comes to samples that are difficult or impossible to digest. Prodigy DC Arc performs elemental analysis of samples in their native form without sample digestion. Samples such as:

  • Ceramics and Glass
  • Metal Oxides, Carbides, Borides, Nitrides
  • Refractory powders such as SiC
  • Graphite Powder
  • Precious Metals & Traces in the Metals
  • Geological Materials
  • Nuclear Materials: Uranium Oxide, Plutonium Oxide
  • Soils, Sludge, Ashes
  • Paints​

For some applications, such as the
measurement of trace elements in
high purity copper, DC Arc 
is one of
the only techniques available that
provide the sensitivity and
ease-of-use 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:

  • Direct analysis of conductive and nonconductive samples
  • Eliminates sample digestions
  • Provides low limits of detection
  • Provides fast quantitative, semi-quantitative or qualitative analysis
  • Captures the full spectrum, performs elemental fingerprinting
  • Inexpensive to operate
  • Inexpensive to maintain​

 DC Arc Technique

With the DC Arc technique, a small amount of sample (typically 20-500mg) is loaded into a cup shaped graphite electrode. The sample electrode and a counter electrode are inserted into the stand and connected to a DC Arc Source.

 Prodigy DC Arc

​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 of a samples 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.
