P2002-RT

Polar pesticides (low levels, babyfood) in milk

The ring test is designed to cover a broad range of polar pesticides in milk.
The polar pesticides are spiked at low concentration levels (about 0.01 mg/kg) in order to reflect a low level contamination, which might be relevant for special purposes like baby food.

The milk sample is spiked with

  • a selection of quaternary ammonium compounds (from BAC C-8 to C-18 and DDAC C-8 to C-12),
  • chlorate,
  • chlormequat and mepiquat,
  • melamine, and
  • glyphosate.

The aim of the ring test is

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

Parameters

BAC C-8, BAC C-10, BAC C-12, BAC C-12, BAC C-14, BAC C-16, BAC C-18, DDAC C-8, DDAC C-10, DDAC C-12, chlorate, chlormequat, mepiquat, melamine, glyphosate
