Cleanert SUL-5

TPH means triple phase SPE for Herb, and it was constituted by three kinds of materials. These three kinds of materials using different mechanism of action, focus on the colorants, organic acid and organic substance, also cosidering different polarity of the interferent, such as nonpolarity substance, substance with hydroxyl and carboxyl group, also the basic group. By mixing different materials together, we achieve a better result of clean up, expecially complicated matrix.

TPH is majorly used for extraction and detection of pesticides from ChineseHerb such as Ramulus Mori, Honeysuckle and the Fruit of Chinese Wolfberry, It can absorb reduce up to 80% interferent and without adsorb any pesticide residues.

Cleanert TPH has been used in China national standard methods, Determination of 488 Pesticide Residues and Related Chemicals Residues and 413 Pesticide Residues and Related Chemicals Residues in the Ramulus Mori, Honeysuckle and the Fruit of Chinese Wolfberry with GS-MS and LC-MS/MS Respectively, Determination of 448 pesticides and related chemicals residues in tea—LC-MS-MS method. The process mainly containing ACN extraction, Load the sample on the pre-actived column, and then eluted by ACN- toluene (3+1).

TPT was constituted by three kinds of materials. These three kinds of materials using different mechanism of action, focus on the colorants, organic acid and tea polyphenols, also considering different polarity of the interferent, such as nonpolarity substance, substance with hydroxyl and carboxyl group, also the basic group. By mixing different materials together, we achieve a better result of clean up, expecially complicated matrix. TPT is majorly used for extraction and detection of pesticides from tea leaf, It can adsorb reduce up to 80% interferent and without adsorbing any pesticide residues.
