产品特点：
Thermo Scientific QuEChERS 萃取产品提供一种方便和有效的方法，用于测定水果、蔬菜和其他食品中残留的农药。
QuEChERS 方法提供的优势包括：高回收率、结果精确、低溶剂和玻璃器具用量、低人力和工作台空间、降低试剂成本等。而程序即稳健又牢固。
QuEChERS 方法是一个二步流程：萃取然后净化。萃取步骤产品使用 MgSO 来帮助萃取，连同 NaCl、柠檬酸钠或无水柠檬酸钠用于“对碱敏感的化合物（例如，灭菌丹或克菌丹）。萃取步骤产品采用 50mL 聚丙烯离心管以方便萃取。净化步骤产品包含 PSA（伯胺/仲胺） ，用于去除其他化合物中的有机酸和极性色素。某些产品将 PSA 与封端 C18 配合使用来去除大多数的脂质和固醇，或连同石墨化碳黑用于去除固醇和色素，例如叶绿素。备有各种试管格式和柱床重量来适应大小样本尺寸。
可测定比标准 SPE 更多的农药
易于使用

Considerations in method development
1) Determine the properties of the pesticides of interest:
* Base sensitive compounds - use extraction product with sodium acetate
* pH dependent
* Non-base sensitive compounds - use extraction product with sodium chloride or sodium citrate
2) Determine the properties of the sample matrix:
* General
* Fatty
* Pigmented
* Highly pigmented
