The user-friendly gas conditioning module NITEX 1 of TE Instruments, is designed for reproducible elimination of interferences during low level sulfur analysis.

The analysis of low level sulfur in hydrocarbon products is nowadays challenged by interferences, which might increase the measured sulfur level dramatically. This could result into wrong decisions in terms of the production or refinery processes.
Unnecessary or corrective shutdowns are expensive. The Sulfur number should be right the first time!



Ask for Quotation


TE Instruments has developed the NITEX 1, a gas conditioning system designed to eliminate specific interferences, which might increase the measured sulfur content.
The NITEX 1 is the ultimate solution for obtaining the exact low level Sulfur number, even in samples containing Nitrogen levels well into the percentage range.


Simple and Easy Operation


TE Instruments NITEX 1 is simply connected in-between the combustion gas stream and the UV-Fluorescence detector.
Just connect the oxygen supply and plug it in.
It’s ready to run.



Robust Performance for Extra Peace of Mind


With TE Instruments NITEX 1, you can rest assured that your samples are handled with the utmost precision and reliability, eliminating all Nitrogen interferences. The NITEX 1 not only provides flexible and user friendly system connection, but it is also robust enough for high sample throughput environments.
The module is suitable for any sulfur analyzer and enables high reproducibility and low detection limits (depending on analyzer performance).


Typical applications


  • in hydrocarbons
  • in pyridine
  • in fuels (cetane improver)



A Complete Solution for your TS UV Fluorescence Analyzer


The NITEX 1 comprises a stand-alone electronic control centre, pressure regulator, a flow controller, an ozone exterminator and a gas mixing vessel.
In addition, it includes all the necessary tubing and hook-ups to enable connection to both combustion system and UV-Fluorescence detector.


Empower your Sulfur Analyzer


The NITEX 1 helps you getting the exact low level Sulfur number.
Nothing more……, nothing less.
