Quantification of the mycotoxins patulin and ochratoxin A by stable isotope dilution assays

摘要

For analysis of trace compounds, stable isotope dilution assays (SIDAs) have gained increasing importance in the past years. This methodology is based on the use of stable isotopically labelled analogues of the analytes as internal standards (IS). To take the mycotoxins patulin and ochratoxin A as examples, the benefits of SIDAs were demonstrated both for foods and for clinical analyses.
