Chemical analysis of additives included in fully formulated oils using high-performance liquid chromatography-tandem mass spectrometry. [PDF]
Rapid Commun Mass SpectromRationale Fully formulated oils (FFOs) are chemically complex petrochemical products composed of base oil and additive mixtures that are employed in automotive engines to provide lubrication. In particular, the additive portion of FFOs is often precisely controlled to tailor the resultant formulation to a specific role.

Atmospheric pressure matrix-assisted laser desorption/ionization mass spectrometry of engine oil additive components. [PDF]
Rapid Commun Mass Spectrom, 2022 Rationale The efficiency of lubricants strongly depends on the content of functional additives. In order to assess the chemical and structural changes taking place in the lubricating oil and its additives during operation, it is essential to develop a method for simple and prompt analysis.
