QuPPe-PO

QuPPe-PO (for products of Plant Origin)

 

QuPPe-PO is a method collection for the analysis of highly polar pesticides in food of plant origin and honey. It involves extraction with acidified methanol and LC-MS/MS measurement. Various LC-MS/MS options are available to chose depending on the scope of analytes to be covered.
