Multi-method pesticides in black tea

P2121-RT is part of the ongoing scheme rolling proof. The scheme is designed for common pesticide multi-residue methods. 
Please feel free to book P2121-RT as a single test 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).
