Wear Metals/Elemental Analysis - Lubricating Oil Analysis
Wear Metals/Elemental Analysis - Lubricating Oil AnalysisElemental analysis is used to evaluate and quantify wear metal elements, additive elements and contamination elements. Wear metals are analyzed to pinpoint problem areas through trend analysis. By analyzing the additive elements, the oil type can ...

Particle Count - Lubricating Oil Analysis
Particle Count - Lubricating Oil AnalysisFluid cleanliness is critical in hydraulic and other systems where high fluid pressure and velocity are involved. Excessive fluid particulate contamination is a major cause of failure of hydraulic pumps, motors, valves, pressure regulators, and fluid controls. ...

Total Base Number (TBN) - Lubricating Oil Analysis
Total Base Number (TBN) - Lubricating Oil AnalysisThe total base number is an expression of the amount of alkaline additives in the lubricant that are capable of neutralizing the acid products of combustion.A new oil starts with the highest TBN it will possess. During the time the lubricant is in service, ...
-
Total Acid Number (TAN) - Lubricating Oil Analysis
Total Acid Number (TAN) - Lubricating Oil AnalysisThe total acid number is the quantity of acid or acid-like constituents in the lubricant. An increase in TAN from that of the new lubricant should be monitored. The TAN of a new oil is not necessarily zero since oil additives can be acidic in nature. ...

Nitration - Lubricating Oil Analysis
Nitration - Lubricating Oil AnalysisNitration products are formed during the fuel combustion process when combustion by-products enter the engine oil during normal operation or as a result of abnormal "blow-by" past the compression rings. These products, which are more common in oils used to lubricate ...

Oxidation - Lubricating Oil Analysis
Oxidation - Lubricating Oil AnalysisLubricating oil in engines and other components combines with available oxygen under certain conditions to form harmful by-products. Heat, pressure, and catalyst materials accelerate the oxidation process. By-products of oxidation form lacquer deposits, corrode metal ...

Fuel Soot - Lubricating Oil Analysis
Fuel Soot - Lubricating Oil AnalysisFuel soot is composed of carbon and is always found in diesel engine oil. Laboratory testing is used to determine the quantity of fuel soot in used oil samples. Stringent exhaust emission regulations have placed greater emphasis on fuel soot levels. One of the most ...
-
Solids - Lubricating Oil Analysis
Solids - Lubricating Oil AnalysisSolids represent a measurement of all solid and solid-like constituents in the lubricant. The makeup of solids depends on the system. In diesel engines, fuel soot is usually the major constituent measured. In non-diesel components, wear debris and oil oxidation products ...

Fuel Dilution - Lubricating Oil Analysis
Fuel Dilution - Lubricating Oil AnalysisFuel dilution of crankcase oil by unburned fuel reduces lubricant effectiveness. The thinning of the lubricant can lead to decreased lube film strength adding to the risk of abnormal wear. Depending on certain variables, when fuel dilution of crankcase oil exceeds ...

Water/Coolant Contamination - Lubricating Oil Analysis
Water/Coolant Contamination - Lubricating Oil AnalysisThe presence of water in engines indicates contamination from outside sources, from condensation of moisture in the atmosphere, or from internal coolant leaks. Water is typically evaporated by engines at normal operating temperatures. However, water ...
