簡要描述：

Merck ZIC-HILIC親水作用色譜柱

親水作用色譜是一種直接分離極性和親水性化合物的色譜技術(shù)，它以親水性的填料作為固定相，以水、有機(jī)溶劑和緩沖液作為流動相洗脫劑。在HILIC方法中，洗脫順序和反相色譜正好相反，即極性越大，保留時(shí)間越長。

Merck ZIC-HILIC親水作用色譜柱

親水作用色譜是一種直接分離極性和親水性化合物的色譜技術(shù)，它以親水性的填料作為固定相，以水、有機(jī)溶劑和緩沖液作為流動相洗脫劑。在HILIC方法中，洗脫順序和反相色譜正好相反，即極性越大，保留時(shí)間越長。

主要特點(diǎn)：

·直接分離極性和親水性化合物
·兩性離子基因通過共價(jià)鍵合在多孔硅膠上
·超長的耐受性使得樣品分離的成本很低

·同時(shí)檢測三聚氰胺和三聚氰酸（FDA推薦使用）

默克的ZIC-HILIC技術(shù)增加了食品的安全性

的美國食品藥物管理局檢測方法使用默克的SeQuant ZIC-HILIC 色譜柱來檢測嬰兒配方奶粉中的三聚氰胺和三聚氰酸成分。

同時(shí)檢測三聚氰胺和三聚氰酸
由FDA所提出的ZIC-HILIC方法提供您一項(xiàng)其它檢測方法*的優(yōu)勢: 受三聚氰胺污染的嬰兒配方奶粉也可能含有其它有毒的三嗪類化合物, 例如三聚氰酸, 它會和三聚氰胺牢固結(jié)合，從而使問題變得更加嚴(yán)重。同時(shí)測定和確認(rèn)嬰兒配方奶粉中的三聚氰胺和三聚氰酸的這項(xiàng)建議可以相當(dāng)程度上增加食品安全性。

近來美國食品藥物管理局（FDA）宣布，通過使用默克的SeQuant ZIC-HILIC色譜柱, 已經(jīng)開發(fā)出一種可同時(shí)檢測嬰兒配方奶粉中三聚氰胺和三聚氰酸殘留物的方法。FDA負(fù)責(zé)管理美國的食品安全事項(xiàng)，其建議方案受到*的關(guān)注且被其它國家的政府機(jī)構(gòu)采納。

這個建議結(jié)合了液相色譜與質(zhì)譜聯(lián)用技術(shù)，使用SeQuant ZIC-HILIC, 即使很低濃度的三聚氰胺和三聚氰酸都可以被準(zhǔn)確的分離和檢測。這兩種分析物的定量極限是0.25 µg/g。因此默克的SeQuant ZIC-HILIC能令人信賴鑒定嬰兒配方奶粉的品質(zhì)。
