Highly polar pesticides in grapes (P1910-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|).

100 g of a spiked grape homogenate is provided as test material. The corresponding unspiked grape homogenate is available upon request.

The homogenate is spiked with

  • chlormequat,
  • ethephon,
  • glyphosate and AMPA, and
  • phosphonic acid (concentration level < 0.1 mg/kg).
