| titleOfInvention | UPLC-MS/MS detection method for establishing fat-soluble shellfish toxin based on graphene QuEChERS method |
| abstract | The invention relates to a UPLC-MS/MS detection method for establishing fat-soluble shellfish toxin based on a graphene QuEChERS method. The invention establishes a UPLC-MS/MS quantitative detection method of 9 fat-soluble shellfish toxins in shellfish aquatic products, which comprises the following steps: the method has the advantages of rapidness, simplicity, convenience, high efficiency, high recovery rate, less organic solvent contact, time saving and the like; the established QuEChERS sample pretreatment technology is combined with the freezing degreasing technology and the high adsorption characteristic of graphene oxide, so that complex matrixes (such as free fatty acid and pigment) can be effectively removed, a better detection recovery rate effect of fat-soluble shellfish toxin is obtained, the purification effect is good, the low-temperature freezing technology is introduced to assist the purification effect of the QuEChERS method on the samples, the matrix benefit can be obviously reduced, and the sensitivity of the method is improved; by combining the ultra-high liquid chromatography tandem mass spectrometry technology, the method successfully applies the detection of the fat-soluble shellfish toxin in the shellfish sample, can simultaneously detect 9 fat-soluble shellfish toxins, obviously increases 5 kinds compared with the existing standard method, and has better applicability. |
