3 Principle
The fumonisin B1 and B2 in the sample are extracted with the extract, purified and enriched by immunoaffinity column, and then derivatized with o-phthalaldehyde, ultra-high efficiency liquid.
The chromatographic fluorescence detector was used for the determination by external standard method.
4 reagents and equipment
Unless otherwise specified, the reagents used are of analytical grade, and the experimental water should meet the requirements of Class I water in GB/T 6682.
