Systems and methods include a computer-implemented method for determining a concentration of hydrocarbon fuel in a fluid sample. A thin Cyclic Olefin Copolymer (COC) film of a COC layer having a honeycomb mesh-pattern forming a conductive metal trace is sputtered. The thin COC film is configured to dissolve upon contact with alkyl aromatic compounds present in hydrocarbon fuels. A fluid sample of a hydrocarbon fuel is positioned in an open area on the thin COC film. A resistivity of the conductive metal trace is monitored. A determination is made in response to the monitoring that a change in resistivity of the conductive metal trace has occurred resulting from dissolution of the thin COC film. A time duration is measured from the positioning of the fluid sample to the resistivity change. A concentration of the hydrocarbon fuel in the fluid sample is determined based on the time duration.
