Mineral oil analyzes include certain analyzes that are routinely performed. Analyzes routinely performed on mineral oils can be listed as follows:
- Fluid Properties
Viscosity
Acid/Base Number
FTIR
Elemental Analysis
- Contamination
Particle Count
Moisture Analysis
Elemental Analysis
- Wear Residues
Iron Density
FTIR
Elemental Analysis
If the general objectives of the analyzes carried out on mineral oils are listed:
Viscosity is an important parameter to monitor in an oil. Depending on the change in viscosity, many negative conditions such as the correctness of the oil used in the machine, oil oxidation, thermal stress can be detected.
The Acid/Base Number is performed for purposes such as detecting problems with contaminants in mineral oils, oil oxidation, the presence of incorrect lubricants, the presence of glycol, whether the oil change process has been extended. Acid/Base Number analysis results are expressed in milligrams of potassium hydroxide volume required to neutralize acids in one gram of oil.
With FTIR, the presence of pollution from fuel, water, glycol and soot, oil degradation products such as oxides, nitrates and sulfates, additives such as zinc dialkyldithiophosphate (ZDDP) and phenols can be detected.
Elemental Analysis is also called wear metal analysis. It is detected by atomic emission spectrophotometer (AES) principles. Its purpose is to detect the concentration of wear metals, contaminants or additives in the oil.
Particle Counting is performed according to the ISO 4406 standard, but can be determined by many different test methods. Its purpose is to detect the size and amount of particles in the oil.
Moisture Analysis, using the Karl Fischer method, aims to determine the moisture content in the oil sample. With moisture detection, it can be interpreted whether there is water ingress from open doors or vents, internal condensation during temperature fluctuations, or gasket leaks.
