What type of contaminants can oil analysis effectively detect?

Oil analysis is particularly effective in detecting contamination from water due to the unique properties and behaviors of water within lubricating oil systems. Water can enter lubrication systems through various means, such as condensation, leaks, or improper handling. When present in oil, water can significantly affect the lubrication properties, leading to issues like rust formation, corrosion, and the breakdown of the oil's lubricating film.

The analysis of oil samples can reveal the presence of water through techniques such as Karl Fischer titration or infrared spectroscopy, which identify moisture levels that could indicate wear or damage to equipment. The detection of water is critical because it can facilitate microbial growth and accelerate the degradation of both the lubricant and the machinery it is meant to protect.

While air, metals, and dust can indeed contaminate oil, the specific techniques and methods used in oil analysis are particularly adept at measuring water content, making it a crucial area of focus for maintaining lubricant integrity and ensuring the longevity of machinery.
