High Level Concentrations Total Nitrogen Analysis with NEXIS and NEXIS VP
Quantifying accurately high concentrations of Total Nitrogen in liquid hydrocarbons and solid samples with a Combustion analyzer is dependent on the controlled combustion process and the linearity of the Chemiluminescence detector (CLD). The NEXIS and NEXIS VP models Total Nitrogen analyzer has applications in a wide range of petroleum products including lubricants, resins and a variety of polymer sample types. Normally high range calibration lines show a second order line, which can have a negative impact on the accuracy of the obtained nitrogen test data. This Application Note shows the performance of the NEXIS product at a wide linear working range, without the need to change from typical PMT settings of the CLD detector or the need to perform separate calibration lines.
TSHR has been helping labs achieve their elemental analysis goals with dedicated solutions. Our vision is to develop innovative reliable combustion analyzers that enable customers to make their work productive and more easier.
To help labs excel we offer Application Notes across the Combustion Analyzer product line. They are a resource that explains the technology, performance, and abilities of our products as used against certain methodologies and or applications.
Whether your needs center around an ASTM Standard or EN/ISO methods, or a sample matrix-based outcome TSHR has you covered. If you don’t see the technical direction you need, simply contact us. We also offer sample analysis in our onsite Applications Lab.
