Abstract Number: 126

The nitrogen content in lubricants is periodically monitored for quality control, as described in ASTM D5291 - the Official Method for carbon, hydrogen, and nitrogen in petroleum products and lubricants.  The Thermo ScientificTM FlashSmartTM Elemental Analyzer (EA), based on the dynamic combustion of the material, requires no sample digestion or toxic chemicals while providing efficient and fully automated nitrogen determination of lubricants. To lower the operational cost, the FlashSmart EA can be operated with Argon instead of helium. Here we demonstrate the analytical performance of the FlashSmart EA and the repeatability according to the Official Method.
