Multi-method pesticides and bromide in walnut

P2424-RT covers pesticides, which are within the scope of common pesticide multi-residue methods. Up to 15 different pesticides are spiked to the test material.

Furthermore, the quantification of inorganic bromide is offered as an additional module. The results related to bromide are assessed with respect to the comparability (z-score). 

The aim of the ring test is

• the correct identification of the spiked multi-method pesticides,
• 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 pesticides.
