Nitrogen Gas Analyser

LD 8000                                                       Trace Nitrogen Analyser

The Online trace Nitrogen in Argon / Helium Analyser for High Purity Argon / Helium is based on unique Plasma Emission Detector. It can detect N2 upto 0.1 ppb. The Trace N2 measurement can be combined with Trace Oxygen, Moisture and Hydrocarbon. Optionally the system can come with an internal  Zero calibration eliminating the need for Zero Gas.


  • Measurement Range :                      0 – 100 ppb min
  • Sensor Technology:                          Plasma Emission Detector
  • Resolution:                                        0.1 ppb


ACCURRA-S 7390                                  Percentage Nitrogen Analyser

Our Online Nitrogen Gas Analyser is based our advanced ACCURRA-S platform.  Accurra-S analyser exceeds the industry expectations on Accuracy, Reliability and cost of ownership.
