P2001-RT

Polar pesticides / contaminants in black tea

Ring test P2001-RT is designed to cover the most frequent polar pesticides and contaminants in black tea. 

The test material consists of black tea (milled, 50 g), spiked with

  • anthraquinone,
  • biphenyl,
  • chlorate and perchlorate,
  • nicotine,
  • glyphosate and AMPA,
  • diquat and paraquat.

The basic module (anthraquinone, biphenyl, chlorate and perchlorate) is included in the price of the ring test. The participants are free to choose the additional modules nicotine, glyphosate and AMPA (module 1) and diquat and paraquat (module 2). 

The analytical data are assessed with respect to

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