Abstract

An apparatus includes a plate and a micro-protrusion baffle. The plate defines a microfluidic channel that is configured to flow a sample of lubrication oil. The microfluidic channel has an inlet for receiving the sample of lubrication oil. The microfluidic channel has an outlet for discharging the sample of lubrication oil. The plate defines walls of the microfluidic channel. The walls extend from the inlet to the outlet. The micro-protrusion baffle is located within the microfluidic channel between the inlet and the outlet. The micro-protrusion baffle extends from any of the walls. The micro-protrusion baffle includes a cyclic olefin copolymer. Dissolution of at least a portion of the micro-protrusion baffle in response to the sample of lubrication oil flowing through the microfluidic channel indicates a presence of hydrocarbon fuel in the sample of lubrication oil.
