Solution highlights

Powerful single wavelength EPD detector

Our mini SePdd was designed for applications that require a single optical wavelength module. With this entry-level enhanced plasma discharge (Epd) detector, the wavelength can be configured to monitor an emission specific to a molecule or to a chemical function group. In tracer mode, it can also be used as a detector with a low-cost argon carrier gas.


Enhanced plasma discharge (Epd)

At the core of our patented EPD technology, a highly energetic plasma source is used to ionize molecules. An EPD-stabilized dielectric barrier discharge (DBD) isolates the discharge electrodes from the ionized plasma, eliminating sputtering, cell inner wall coating and analyte interference. The result is unsurpassed performance.

Key features of the technology:

  • Discharge cell available in metal or ceramic
  • Unique compound electrode that can withstand high temperatures, high pressure, and sub-atmospheric pressure
  • Plasma stabilization and electron injection electrodes
