The immunoaffinity column can selectively adsorb Zearalenone/Deoxynivalenol and has a highly targeted purification effect. Samples that have passed through the column for purification may be used in HPLC, LC-MS/MS and other devices for analysis after concentrating with nitrogen gas.

Affinity columns can be used in combination with HPLC or LC-MS/MS to achieve rapid testing, and to increase signal-to-noise ratio and improve the accuracy of the detection method.

The basis of the measurement is the antigen-antibody reaction. Antibodies are connected to the column and the toxins in the sample are extracted, filtered, and 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 eluted, blown dry with nitrogen, redissolved and then injected into the analytical instrument for detection.
