| titleOfInvention | Method for enriching clenbuterol, ractopamine and salbutamol in urine sample of breeding livestock |
| abstract | The present invention discloses a method for enriching clenbuterol, ractopamine and salbutamol in a urine sample of breeding livestock, and relates to the field of analytical chemistry, particularly to a sample pretreatment method. The method comprises: carrying out a sample pretreatment, adding sulfonic group surface-modified polystyrene superparamagnetic nanometer beads or sub-micron beads to adsorb, carrying out elution, and collecting the eluent, wherein the elution solution can be directly used for liquid chromatography-mass spectrometry to quantitatively analyze contents of clenbuterol, ractopamine and salbutamol. The method has characteristics of simple operation process, high extraction recovery rate, less elution solvent use amount, and no requirement of rotary evaporation. |
