Abstract:
Lubricant oils are used in many commercial settings, from the automotive and aerospace industries, to oil well drilling rigs, to specialist metalworking machinery; in fact, lubricant oils may be present in any application where surfaces might contact one another and friction become a problem. Many different formulations of lubricant oils are manufactured to address their wide range of uses.
High resolution mass spectrometry enables the accurate mass measurement of ions from which molecular information may be derived. The specificity of the approach is further enhanced by ion-mobility which provides information related to the size, shape and charge of the ions.
A simple workflow, combing ion-mobility with high resolution mass spectrometry followed by statistical analysis of the acquired data, is presented. This technique is used to discover differences between five automotive lubricant oils at the molecular level. This approach could be used to compare similar products, understand the differences between poorly and correctly performing oils, or deformulate competitors’ products.
