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.
DC Arc Source
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 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 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.
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.

The Prodigy DC Arc will enhance materials testing capabilities for many labs by providing low detection limits and fast turn-around times for a virtually unlimited number of elements in even the most challenging sample matrices.
The DC Arc technique is used for a wide range of applications in the following industries:
