Compact online trace N2 in argon/helium analyser with Enhanced plasma discharge (Epd) technology*

The N2Sense analyser is based on our Enhanced plasma discharge (Epd) technology*. Compared to other commercially available plasma-based analysers, which use a single wavelength measurement, the N2Sense uses a combination of our unique focusing/stabilising and electron injection electrodes with a spectral compensation optical measurement to improve performance and signal stability.

Reach analytical performance with an industrial/instrumentation double ferrule compression fitting
By using LipLOK on your instruments benefit from:

  • Leak detection capability

  • Better leak integrity

  • No dead volume

  • Backward compatible with Swagelok double ferrule standard

First, two stabilising/focusing electrodes* have been introduced in the design to resolve plasma source instability (quenching and filamentary oscillation) and hence signal to noise improvement at low concentration.

Second, the electron injection electrodes* improve ionisation efficiency.

Stabilising and focusing electrodes, Enhanced design of Plasma Emission Detector PED, Epd Technology
  • Unique to our Epd technology* and to our proprietary spectral compensation algorithm*.


  • Cancel measurement drift from ambient pressure, flow and temperature variations.

  • The result is an unsurpassed measurement precision

Proprietary trap

Our new trap is made of a proprietary material (not molecular sieve). It offers a better absorption to moisture, hydrocarbons and organic compounds. As it has no affinity to N2 but absorb hydrocarbons and organic compounds, it does not delay the response and resolve the problem of the former technology.


A special doping compounds (H2O + proprietary compounds) is added to the plasma. In combination with the focusing/stabilising and electron injection electrodes, this compound helps to further stabilise the plasma discharge and improve the plasma deexcitation process by which photons are emitted for the optical measurement.
