Polar pesticides in ice cream

P2210-RT covers the polar pesticides chlorate and perchlorate as well a selection of quaternary ammonium compounds (BAC C-8 to C-18 and DDAC C-8 to C-12).

The aim of the ring test is

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

Reporting limits of 0.01 mg/kg are required for all parameters.
