Recently, an environmental protection organization released an investigation report on tea pesticides, questioning the pesticide residues contained in the products of the nine major tea companies in China, which triggered a public controversy about whether they can still drink tea. With reference to the national standard, Dima Technology quickly launched a solution for the detection of multiple pesticide residues in tea. After the samples were extracted with acetonitrile, they were purified by ProElut TPC special solid-phase extraction columns for tea, and detected by GC-MS. The method is accurate and reliable, and can achieve the determination of multiple pesticide residues in tea.
