P2108-RT

Polar pesticides / contaminants in green tea

Ring test P2108-RT is designed to cover the most frequent polar pesticides and contaminants in green tea. 

The test material consists of green tea (milled, 100 g), spiked with

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

The basic module (anthraquinone, biphenyl, chlorate, perchlorate, and nicotine) is included in the price of the ring test. The participants are free to choose the additional modules glyphosate, AMPA, and trimesium (module 1), diquat and paraquat (module 2), and matrine and oxymatrine (module 3). 

The analytical data are assessed with respect to

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