Abstract:
Lubricating oils are the lifeblood of oil-wetted machinery. Elements such as barium, boron, calcium, copper, magnesium, molybdenum, phosphorus, sulfur, and zinc are used as additives in lubricating oils to improve their lubricating capability and properties. The quantity of those elements highly affects a lubricant’s performance. Therefore, a rapid, sensitive, and precise measurement is crucial as part of its production. In this paper, ASTM D4951 and D5185 methods are demonstrated with Analytik Jena’s PlasmaQuant® 9100 Elite, equipped with an organic sample introduction kit. The ASTM D4951 covers eight elements and can be used to determine if additive packages and unused lubricating oils meet specifications with respect to their elemental composition. ASTM D5185 method is designed for used and unused oil samples, identifying 22 additives, wear metals, and contaminants.
