| titleOfInvention | The sample-pretreating method and assay method of sulfa drugs in a kind of measure formula milk |
| abstract | The invention provides a kind of sample-pretreating method for determining sulfa drugs in formula milk, comprise the following steps：Formula milk sample is weighed, acetic acid aqueous solution is first added, mixes, adds methanol, is centrifuged after mixing；By supernatant methanol removed by evaporation, acetic acid aqueous solution is added, that is, obtains diluting extract solution；By the dilution extract solution by solid-phase extraction column, then with water wash solid-phase extraction column and discard efflux；Then eluted with methanol, collect and obtain scavenging solution；And be evaporated the scavenging solution, methanol aqueous solution is added, redissolution liquid is produced, liquid is then redissolved through membrane filtration, that is, obtains prepare liquid.Present invention also offers a kind of assay method of sulfa drugs in formula milk, the prepare liquid is detected with UPLC MS methods.Method of the present invention handy and safe, can meet analysis requirements of one's work. |
