There are many derivative detection methods for aflatoxin, most of which are pre column trifluoroacetic acid derivatives or post column iodine chemical derivatives. However, due to the cumbersome preparation of derivative reagents and complex instrument operation, these methods are increasingly being replaced by photochemical derivatives.
There are many derivative detection methods for aflatoxin, most of which are pre column trifluoroacetic acid derivatives or post column iodine chemical derivatives. However, due to the cumbersome preparation of derivative reagents and complex instrument operation, these methods are increasingly being replaced by photochemical derivatives. The Huang Aflatoxin Analysis Liquid Chromatography System launched by Dalian Yilite Analytical Instrument Email Company uses photochemical derivatization method for detection. This method has the advantages of easy operation, no need for derivatization reagents, avoiding contact with du reagents, and environmental friendliness.
