| titleOfInvention | The isolation and determination method of dicyandiamide components in dairy products |
| abstract | The invention discloses the isolation and determination method of dicyandiamide components in a kind of dairy products, comprise testing sample preparation, purification, detect and recovery experiment; Aqueous formic acid is added in dairy products, and obtain liquid to be checked through microwave abstracting, and it is centrifugal after through Solid-Phase Extraction, successively through water drench and eluting solvent wash-out obtain eluent, obtain testing sample solution by after eluent evaporation and concentration with acetonitrile solvent dilute filtration; The standard working solution of configuration ladder concentration, the difference sample introduction on liquid chromatography-tandem mass spectrometry instrument by testing sample solution and standard working solution, obtains working curve and mass spectrogram, by working curve and mass spectrogram qualitative and quantitative analysis; Then take the dairy products that dicyandiamide content is determined, record dicyandiamide concentration successively through above-mentioned experimental procedure, measured value and determined value being calculated the recovery is 83.6 ~ 95.7%.The present invention has extraction efficiency high, accurate qualitative, quantitative mensuration, highly sensitive, result advantage accurately. |
