Abstract:

Stable isotope dilution assay (SIDA) is a calibration technique that can be used to offset matrix effects. However, care must be given to choosing appropriate internal standards. This article demonstrates the importance of using a labeled internal standard that matches the target analyte for mycotoxins analysis.
