| titleOfInvention | A kind of detection method of arsanilic acid, nifediarsenic acid and roxarsine in eggs |
| abstract | The invention relates to a method for the determination of arsanilic acid, nifediarsenic acid and roxarsone in eggs by liquid chromatography tandem mass spectrometry, and belongs to the field of residue detection. Add 1% formic acid water-acetonitrile (30:70, V/V) to the extraction solution to the sample to be tested, vortex and mix, centrifuge, repeat the extraction twice, combine the supernatant, defatted with n-hexane, and concentrated to less than 40°C by rotary evaporation. 3mL, dilute to 5mL with 10% methanol aqueous solution, centrifuge, filter the supernatant through membrane, and use high performance liquid chromatography-tandem mass spectrometer for determination. The invention has high accuracy, precision and sensitivity, and fills the blank of simultaneous detection of three kinds of organic arsine preparations in eggs. |
