dSPE is used to clean up extracted samples of these substances in QuECHeRS (“catchers”) analysis. (-5[1])Differences in the MRLs of these substances especially affect exports in developing countries. Temperature inversions can accelerate “drift” in volatile examples of these substances like Dicamba.
