rolling proof - module tea and spices

P2323-RT is part of the ongoing scheme rolling proof - module tea and spices.

The scheme is designed for common pesticide multi-residue methods and the “difficult and unique commodities” teas and spices according to SANTE11312/2021. 

Please feel free to book P2323-RT individually (please place your order below) or feel free to join rolling proof. If rolling proof is booked as a 5-year-package, a discount of 5 % is granted.

The test material is spiked with 25 to 35 pesticides. Neither the identity nor the exact number of pesticides are announced in advance. The scope of pesticides is defined here.

The analytical data are assessed with respect to

  • the correct identification of the spiked pesticides,
  • the comparability (z-score), and
  • the trueness (70 to 120% of the spiked level).
