Method and equipment for separating and detecting organo-mercuric compound content

The invention provides a test method for organic mercury compounds, which comprises the following steps: first the organic mercury sample and separates the sample are extracted through high performance liquid chromatography, the mobile phase of which comprises:2-mercaptoethanol, one or more lower fatty acids and lower fatty acid salts, leads the chromatographic column draw off to cause chemical reaction under the ultraviolet light, the reaction solution is mixed with inert gases, the gas-liquid mixture is separated through a gas-liquid separator, the highly performance liquid chromatography chart is obtained through testing the separated sample gas phase through atomic fluorescence spectrometer; according to the standard curve between the organic mercury density and the peak area, the organic mercury concentration in the sample to be tested is figured out through the separated sample gas phase peak area in the highly performance liquid chromatography chart. The invention provides a separating and testing method for a plurality of organic mercury in the sample to be tested.
