QuEChERS 農(nóng)殘SPE（提取部分）

Convenient and effective approach for determining pesticide residues in fruit, vegetables and other foods

QuEChERS 簡介:

QuEChERS 產(chǎn)品的設(shè)計(jì)意在克服高水分含量食品中多種農(nóng)藥殘留的問題，其名稱為Quick-Easy-Cheap-Effective-Rugged- Safe的縮寫。其將多個處理過程簡化、并擴(kuò)大的提取范圍，是進(jìn)行農(nóng)殘分析的理想選擇。

QuEChERS S方法分為兩個步驟：提取后提純。
提取產(chǎn)品使用MgSO4連同NaCl或者無水醋酸鈉（用于對基體敏感的組分，如滅菌丹、克菌丹等）去除樣品中的水分，包裝為50mL聚丙烯離心管，方便提取。

提純產(chǎn)品包含PSA （伯胺或仲胺）來去除有機(jī)酸和極性色素，一些產(chǎn)品中還將封尾C18和PSA組合來去除脂肪和固醇，或采用多孔石墨化碳來去除固醇和色素（如葉綠素）

優(yōu)勢：

★ 高通量—30分鐘內(nèi)分析8個樣品

★ 回收范圍廣（極性樣品、pH依賴性樣品），與傳統(tǒng)的SPE方式相比可分析較多的農(nóng)殘組分

★ 無需繁瑣的操作步驟和自動化設(shè)備

★ 減少溶劑的使用

★ 防止可能污染物的污染

★ 高回收率與準(zhǔn)確的結(jié)果

★ 易用性好，并且有多種組合可選擇，方法開發(fā)便捷
