1. A device for detecting mercury isotopes in an oil-gas source, comprising:

  • at least one enrichment-absorption system for mercury in crude oil/hydrocarbon source rock, an enrichment-absorption system for mercury in natural gas and at least one secondary purification-enrichment system for mercury;

    the enrichment-absorption system for mercury in crude oil/hydrocarbon source rock comprises three air-absorption bottles, a pyrolysis/cracking system, five impact samplers, and a vacuum pump, which are connected in series by pipe lines;

    the enrichment-absorption system for mercury in natural gas comprises five impact samplers connected in series, wherein the first impact sampler is connected to the natural gas outlet from the natural gas well and the last impact sampler is connected to the cumulative gas flow meter;

    the secondary purification-enrichment system for mercury comprises a nitrogen-gas cylinder, a collection bottle with potassium permanganate absorption liquid in which mercury isotope is absorbed, and a secondary enrichment-absorption bottle containing an acidic aqueous potassium permanganate solution, which are connected in series by pipe lines, wherein the secondary purification-enrichment system further comprises a stannous-chloride storage bottle, which is connected to a pipe line between the nitrogen-gas cylinder and the collection bottle with potassium-permanganate absorption liquid via a peristaltic pump and through a pipe line.
