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.
Our Impact
EST Analytical has been helping labs achieve their analytical goals for over 30 years. Our vision is to engineer reliable laboratory instruments that enable partners to make the world a better place.
To help labs excel we offer Application Notes across our entire 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 a USEPA method, an ASTM Standard, or a sample matrix-based outcome EST 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.
