Multi-method pesticides and polar pesticides in soy bean meal (feed)

Soy bean meal is the most important protein feedstuff worldwide.

P2416-RT offers the opportunity to check the most relevant analytical methods for pesticides in soy bean meal in one ring test.

The participants are free to choose from different modules:

  • related to pesticide multi-residue methods and acidic herbicides (free acids),
  • related to glyphosate, glufosinate and all related metabolites,
  • related to chlorate, perchlorate, and phosphonic acid, and
  • related to diquat and paraquat.

The aim of the ring test is

  • the correct identification of the spiked multi-method pesticides and acidic herbicides,
  • 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).

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