Cleanert® TPT® constitutes three type of materials, which employ different mechanisms to get rid of the interferences such as colorants, organic acids, polyphenols as well as nonpolar matrix.

• It is comprised of graphitized carbon black (Pesticarb), Polyamine silica and amide polystyrene
• Good repeatability and reproducibility were also observed
• It detects 103 kinds of pesticides in valid recoveries range
• It can reduce 90% of the colorants in tea leaves

It is developed for determination of residues of 653 Multi class Pesticides and Chemical Pollutants in Tea, which has been recommended by AOAC official method and Chinese National Standard Method.

By mixing different materials together, we can achieve a better cleanup result for complicated sample matrices.
