Abstract
Hydrocarbon contaminant detection system using polymer film includes a sensor assembly, a syringe, a heater assembly and a controller. The sensor assembly includes a cyclic olefin copolymer (COC) film including electrically conductive materials, and can complete an electrical circuit. The COC film can dissolve in a presence of a hydrocarbon contaminant, breaking the electrical circuit. The syringe can carry a lubrication oil sample to be tested using the sensor assembly. The syringe is operable to contact the lubrication oil sample with the COC film of the sensor assembly. The heater assembly can heat the lubrication oil sample before the lubrication oil sample is loaded to the syringe. The controller can perform operations including operating the syringe to flow the heated lubrication oil sample onto the COC film of the sensor assembly at a pre-determined flowrate.
