Merck ZIC-HILIC亲水作用色谱柱
亲水作用色谱是一种直接分离极性和亲水性化合物的色谱技术，它以亲水性的填料作为固定相，以水、有机溶剂和缓冲液作为流动相洗脱剂。在HILIC方法中，洗脱顺序和反相色谱正好相反，即极性越大，保留时间越长。
主要特点：
·直接分离极性和亲水性化合物
·两性离子基因通过共价键合在多孔硅胶上
·超长的耐受性使得样品分离的成本很低
·同时检测三聚氰胺和三聚氰酸（FDA推荐使用）
默克的ZIC-HILIC技术增加了食品的安全性
的美国食品药物管理局检测方法使用默克的SeQuant ZIC-HILIC 色谱柱来检测婴儿配方奶粉中的三聚氰胺和三聚氰酸成分。
同时检测三聚氰胺和三聚氰酸
由FDA所提出的ZIC-HILIC方法提供您一项其它检测方法*的优势: 受三聚氰胺污染的婴儿配方奶粉也可能含有其它有毒的三嗪类化合物, 例如三聚氰酸, 它会和三聚氰胺牢固结合，从而使问题变得更加严重。同时测定和确认婴儿配方奶粉中的三聚氰胺和三聚氰酸的这项建议可以相当程度上增加食品安全性。
近来美国食品药物管理局（FDA）宣布，通过使用默克的SeQuant ZIC-HILIC色谱柱, 已经开发出一种可同时检测婴儿配方奶粉中三聚氰胺和三聚氰酸残留物的方法。FDA负责管理美国的食品安全事项，其建议方案受到*的关注且被其它国家的政府机构采纳。
这个建议结合了液相色谱与质谱联用技术，使用SeQuant ZIC-HILIC, 即使很低浓度的三聚氰胺和三聚氰酸都可以被准确的分离和检测。这两种分析物的定量极限是0.25 µg/g。因此默克的SeQuant ZIC-HILIC能令人信赖鉴定婴儿配方奶粉的品质。
