Total Nitrogen Analyzer

Designed to meet the specific needs of petroleum refineries, this nitrogen analyzer was developed in collaboration with TOTAL Research Center.
This participation of the end user in its design justifies it’s high level of performance, robustness and ease of use.

 

It allows to:

  • Automatically and rapidly measure the very low nitrogen contents of petroleum products, up to 30 ppb (under certain conditions of use, the performances obtained can be significantly higher than those announced)
  • Measure high nitrogen concentrations, up to 10% in all types of samples (solid, liquid, gas)

 

Nitrogen analyzer by Chemiluminescence, according to ASTM D4629, ASTM D6069…

It can be combined with the injector or liquid automatic sampler, or the Gas / LPG sampler.
