Chemical analysis of additives included in fully formulated oils using high-performance liquid chromatography-tandem mass spectrometry.

ABSTRACT:

Rationale

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. Analysis of the additive composition of both used and unused FFOs is therefore of great importance within the petroleum, automotive, and wider engineering industries.

Methods

A simple and rapid reversed-phase high-performance liquid chromatography-tandem mass spectrometry method is reported herein for the analysis of a range of additives commonly encountered in FFO samples. Mass spectrometry was performed using an LTQ Orbitrap XL instrument using both positiv
