Determination of enols by ultra performance liquid chromatography
1 Scope
This standard specifies the principle, reagents and instruments for the determination of deoxynivalenol by ultra performance liquid chromatography in food and its products.
Preparation, analysis steps, results calculations, etc.
This standard applies to the determination of deoxynivalenol in food and its products.
The detection limit of the standard method for deoxynivalenol is 0.05 mg/kg, and the limit of quantification is 0.15 mg/kg.
