Asphaltenes can pose serious problems for crude oil producers and pipelines, by increasing viscosity of the crude and potentially fouling pipelines and equipment. Here we present a new advance in relatively low-cost on-line electron spin resonance sensor technology which enables continuous, on-line measurement of asphaltene and vanadium concentration in crude oil. Detection limits of 0.1% asphaltene and 5 ppm vanadium are demonstrated in a broad range of crude oils.
