Remarks Ring test P2314-RT is designed to cover the most frequent polar pesticides and contaminants in green tea. The test material consists of black tea (milled, 100 g), spiked with - anthraquinone, - biphenyl, - chlorate and perchlorate, - nicotine, - glyphosate, AMPA, and trimesium, - diquat and paraquat, - matrine and oxymatrine, and - ethylene oxide/2-chloroethanol. 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), matrine and oxymatrine (module 3), and ethylene oxide (module 4). The analytical data are assessed with respect to - the comparability (z-score), and - the trueness (70 to 120% of the spiked level, as far as scientifically reasonable).
