Polar pesticides in strawberries (P1811-RT)

The ring test is designed to cover a broad range of
highly polar pesticides.

The aim is

  • the correct quantification with respect to the
    trueness criterion (70-120 % recovery of the spiked level).
  • the correct quantification with respect to the
    comparability criterion (z-score ≤ |2|).

Change of matrix:
Since organic grapes are not available on the market in May 2018 the matrix grapes is changed to strawberries. 100 g of a spiked strawberry homogenate is provided as test material.

The homogenate is spiked with
