Highly polar pesticides in orange (P1907-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 orange homogenate is provided as test material. The corresponding unspiked orange homogenate is available upon request.

The homogenate is spiked with

  • chlorate and perchlorate,
  • ethephon,
  • a selection of quaternary ammonium compounds
    (BAC C8 - C18 and DDAC C8 - C12), and
  • phosphonic acid (concentration level > 0.1 mg/kg).
