The invention relates to the technical field of octafluoropropane detection, in particular to an electronic-grade octafluoropropane detection method, electronic-grade octafluoropropane is detected by adopting a GOW-MAC helium ionization gas chromatograph, meanwhile, a gas path structure is a double-blowback gas path, the gas path is made of passivated stainless steel, a separation part is adopted, a chromatographic column is also made of passivated stainless steel, and the chromatographic column is a chromatographic column made of a passivated stainless steel material. A sample injection valve of the flame photometric chromatograph is made of a sulfur passivation material, the problem of sulfide analysis and adsorption is solved, a four-valve four-column double-blowback system is adopted, five paths of carrier gas are provided, pipe valve paths through which all samples flow are anti-corrosion gas paths, the helium ionization gas chromatograph and a specific gas path system are emphatically utilized, and the
