While we have not yet fully experimented with this ourselves, determining the quality of oils should be feasible providing the corresponding molecular sensing models and applications are developed. Any oil component which is below a concentration of 1% will not be detectable by SCiO. In addition, as SCiO is currently designed for the scanning of solid samples, the SCiO Liquid sampling accessory (available soon) is required in order to accurately scan liquids.
This may be developed in the future either by us or by the SCiO developer community using our SCiO DevKit, which allows users to create models and apps.
