Determination of Pesticides in Wine
Tyler Trent, Teledyne Tekmar
This study will evaluate the performance of the AutoMate-Q40 by monitoring multiresidue pesticides in wine. The target pesticides found in the wine will be determined by high performance liquid chromatography-tandem mass spectrometry (HPLC–MS-MS). The AutoMate-Q40 instrument streamlines the QuEChERS method, from adding acetonitrile (ACN) and buffering salts, shaking, mixing, centrifuging the sample, transferring to a dispersive solid phase extraction (d-SPE) tube, and finally measuring and delivering the extract. These advances in automation will greatly improve laboratory production. Read more. |
