Analyzing Water in Oil
High water content of lubricating oils negatively impacts the operation and longevity of the oils and the mechanical equipment components being lubricated. Additionally, water has been known to cause certain oil additives to precipitate out, as well as to chemically attack some additives. Some of the modes by which water exists in lubricating oils can lead to catastrophic equipment failure. These include corrosion, erosion, etching and hydrogen embrittlement. Water in oils can occur in dissolved, emulsified and free states.

Water contamination is detrimental to any lubricant. A measured amount of oil is introduced into a titration chamber. This solution is titrated with Karl Fischer reagent to a specific endpoint. The amount of reagent used and the sample volume are calculated and converted to ppm or percent by mass.
