The immunoaffinity column can selectively adsorb Aflatoxins (B1,B2,G1,G2)/Ochratoxin A/Fumonisins/Sterigmatocystin from the sample solution, thereby having a highly targeted purification effect on the sample. The sample solution that has been purified by passing through the affinity column can be directly used for HPLC analysis or for LC-MS/MS analysis after concentrating with nitrogen gas and resuspended.

The basis of the measurement is the antigen-antibody reaction. Antibodies are connected to the column and the toxin in the sample is extracted, filtered, and diluted, and then passed slowly through the immunoaffinity column. The toxins bind to the antibodies in the column and the immunoaffinity column is then washed to remove other unrelated substances that have not been bound. The toxins are then eluted with eluent and injected into an analytical instrument for detection.
