NexiS Total Nitrogen & Sulfur Analyser

The Nexis GM is designed to introduce safe, accurate and reliable measurement of your Gas and LPG samples for trace level Total Nitrogen and Total Sulfur.The Nexis GM is designed with 2 fast connectors to connect a Gas or LPG sample cylinder easily and safely to the sampling valve of the Nexis GM, with a fixed volume for automatic sample introduction into the Nexis TN/TS Analyzer.

The Nexis GM is equipped with one sample loop with a volume of 10 mL for gas and one loop with 100 uL for liquefied gas (LPG) samples, which have multiple automatic injection capabilities.

After the pressurized sample cylinder is connected to the sample introduction port of the Nexis GM the user just presses the start button in the NexisLink software to start the analysis. A customer calibration line can be prepared easily to support routine Gas and LPG analyses.

Regulatory bodies all over the world have set challenging low levels of allowed Sulfur concentration in organic fuels for the present and near future. Beside Sulfur, the Nitrogen content in fuels is attracting a lot of attention, in order to protect the environment.
