QuEChERS 农残SPE（提取部分）
Convenient and effective approach for determining pesticide residues in fruit, vegetables and other foods
QuEChERS 简介:
QuEChERS 产品的设计意在克服高水分含量食品中多种农药残留的问题，其名称为Quick-Easy-Cheap-Effective-Rugged- Safe的缩写。其将多个处理过程简化、并扩大的提取范围，是进行农残分析的理想选择。
QuEChERS S方法分为两个步骤：提取后提纯。
提取产品使用MgSO4连同NaCl或者无水醋酸钠（用于对基体敏感的组分，如灭菌丹、克菌丹等）去除样品中的水分，包装为50mL聚丙烯离心管，方便提取。
提纯产品包含PSA （伯胺或仲胺）来去除有机酸和极性色素，一些产品中还将封尾C18和PSA组合来去除脂肪和固醇，或采用多孔石墨化碳来去除固醇和色素（如叶绿素）
优势：
★ 高通量—30分钟内分析8个样品
★ 回收范围广（极性样品、pH依赖性样品），与传统的SPE方式相比可分析较多的农残组分
★ 无需繁琐的操作步骤和自动化设备
★ 减少溶剂的使用
★ 防止可能污染物的污染
★ 高回收率与准确的结果
★ 易用性好，并且有多种组合可选择，方法开发便捷
