All our detection systems use a technology mastered by Proengin: Flame Spectrophotometry. It consists in analyzing the light spectrum of particles passed through a flame in which burns the gas or the particles to be detected.

The detector operates by passing a continuous stream of air through a burner where it is combusted by in the hydrogen flame (Proengin detectors are intrinsically safe). The light from the flame is passed to a diffraction grating and split into its various colors. These colors are then passed onto a detection grid. The various colors in the flame and their luminosity are measured and processed in real time.

Atomic elements or chemical liaisons have a specific light spectrum. Phosphorus, Sulphur, Arsenic, H-N=O chemical liaison, Potassium, Sodium, Calcium and many other elements thus can be detected without mistake from any gas, aerosol, dust or particle. Proengin Detectors use this principle to detect those specific elements that are present in Chemical Warfare Agents or in Toxic Industrial Materials:

  • All nerve agents such as Sarin, Soman, Tabun or Vx contain phosphorus;
  • All Blister agents such as mustard gas and lewisite contain either Arsenic or sulphur.
  • All Blood agents contain arsenic or emit a HNO molecule when burned into an hydrogen flame.
  • This technology offers the ability to detect an unlimited number of gases as it is not subject to the limitations of a library.
