Total Nitrogen in Lubricating Oils by NEXIS TN Analyzer in Accordance with ASTM D5762 Method

Motor oil being poured from bottle.

ASTM D5762 is an established method for the determination of nitrogen in lubricating oils by oxidative boat inlet chemiluminescence technique. The application is of significant importance because nitrogen components can contaminate refinery catalysts. The determination of nitrogen concentration in lubricant oils is a measure of the total nitrogen in various additives. This application notes describes the principle of operation and obtained analysis results using the NEXIS TN analyzer model, which benefits the customer from ease-of-use, precise total nitrogen data en fast analysis times.
