ZIC® -HILIC亲水作用色谱柱Merck ZIC-HILIC 亲水作用色谱柱● 直接分离极性和亲水性化合物● 两性离子基团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● ZIC-pHILIC，聚合物基质，PH2-10什么是亲水作用色谱（HILIC）：亲水作用液色谱（Hydrophilic Interaction LiquidChromatography，HILIC）是一种直接分离极性和亲水性化合物的色谱技术，为了便于理解，我们可以把它看作为是一种反相色谱溶剂做为流动相的正相色谱。因此HILIC是：● 亲水性的固定相● 以水、有机溶剂和缓冲液作为流动相洗脱剂为什么使用HILIC?尽管反相液相色谱（RPLC）是至今应用最广的色谱分离技术，它能与各种常规的检测方法结合，解决多种分析应用问题，但对某些分析物，特别是极性和亲水性化合物却无法或很少保留。长期以来，人们采用正相液相色谱（NPLC），并使用不利环保的非水溶性流动相如己脘或环己脘来分析这些物质。但是在这种实验条件下，很多极性和亲水化合物往往很难溶解，从而限制了NPLC的应用范围。从现在起有了另一种新的解决办法，即选用亲水作用液相色谱-HILIC。常见的HILIC方法采用50-90%有机溶剂和一定比例的水，并且含有低浓度的缓冲盐。如乙腈/水/醋酸铵体系在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。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无法比拟的优势: 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，其建议方案受到全世界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0.25μg/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。订货信息：分析柱货号描述固定相规格1.50434.0001ZIC® -HILIC （5μm） 14 x 1 mm PEEK 保护柱（5 件）fitting guard column1.50435.0001ZIC® -HILIC（5μm）20 x 2.1 mm PEEK 保护柱（1 件）fitting guard column1.50436.0001ZIC® -HILIC （5μm）20 x 2.1 mm PEEK 保护柱套件（3 件） fitting guard column1.50439.0001ZIC® -HILIC （3.5μm, 100?） 20 x 2.1 mm PEEK HPLC column1.50440.0001ZIC® -HILIC （3.5μm, 100?） 50 x 2.1 mm PEEK HPLC column1.50441.0001ZIC® -HILIC （3.5μm, 100?） 100 x 2.1 mm PEEK HPLC column1.50442.0001ZIC® -HILIC （3.5μm, 100?） 150 x 2.1 mm PEEK HPLC column1.50444.0001ZIC® -HILIC （3.5μm, 100?） 150 x 4.6 mm PEEK HPLC column1.50443.0001ZIC® -HILIC （3.5μm, 100?） 250 x 2.1 mm PEEK HPLC column1.50445.0001ZIC® -HILIC （3.5μm, 200?） 50 x 2.1 mm PEEK HPLC column1.50446.0001ZIC® -HILIC （3.5μm, 200?） 50 x 4.6 mm PEEK HPLC column1.50447.0001ZIC® -HILIC （3.5μm, 200?） 100 x 2.1 mm PEEK HPLC column1.50448.0001ZIC® -HILIC （3.5μm, 200?） 150 x 2.1 mm PEEK HPLC column1.50449.0001ZIC® -HILIC （3.5μm, 200?） 150 x 4.6 mm PEEK HPLC column1.50450.0001ZIC® -HILIC （5μm, 200?） 50 x 2.1 mm PEEK HPLC column1.50451.0001ZIC® -HILIC （5μm, 200?） 50 x 4.6 mm PEEK HPLC column1.50452.0001ZIC® -HILIC （5μm, 200?） 100 x 2.1 mm PEEK HPLC column1.50453.0001ZIC® -HILIC （5μm, 200?） 100 x 4.6 mm PEEK HPLC column1.50454.0001ZIC® -HILIC （5μm, 200?） 150 x 2.1 mm PEEK HPLC column1.50455.0001ZIC® -HILIC （5μm, 200?） 150 x 4.6 mm PEEK HPLC column1.50457.0001ZIC® -HILIC （5μm, 200?） 250 x 2.1 mm PEEK HPLC column1.50458.0001ZIC® -HILIC （5μm, 200?） 250 x 4.6 mm PEEK HPLC column1.50656.0001SeQuant® ZIC® -cHILIC （3μm,100?） 50 x 2.1 mm PEEK HPLC Column1.50657.0001SeQuant® ZIC® -cHILIC 3μm,100?

ZIC® -HILIC亲水作用色谱柱Merck ZIC-HILIC 亲水作用色谱柱● 直接分离极性和亲水性化合物● 两性离子基团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● ZIC-pHILIC，聚合物基质，PH2-10什么是亲水作用色谱（HILIC）：亲水作用液色谱（Hydrophilic Interaction LiquidChromatography，HILIC）是一种直接分离极性和亲水性化合物的色谱技术，为了便于理解，我们可以把它看作为是一种反相色谱溶剂做为流动相的正相色谱。因此HILIC是：● 亲水性的固定相● 以水、有机溶剂和缓冲液作为流动相洗脱剂为什么使用HILIC?尽管反相液相色谱（RPLC）是至今应用最广的色谱分离技术，它能与各种常规的检测方法结合，解决多种分析应用问题，但对某些分析物，特别是极性和亲水性化合物却无法或很少保留。长期以来，人们采用正相液相色谱（NPLC），并使用不利环保的非水溶性流动相如己脘或环己脘来分析这些物质。但是在这种实验条件下，很多极性和亲水化合物往往很难溶解，从而限制了NPLC的应用范围。从现在起有了另一种新的解决办法，即选用亲水作用液相色谱-HILIC。常见的HILIC方法采用50-90%有机溶剂和一定比例的水，并且含有低浓度的缓冲盐。如乙腈/水/醋酸铵体系在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。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无法比拟的优势: 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，其建议方案受到全世界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0.25μg/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。订货信息：分析柱货号描述固定相规格1.50434.0001ZIC® -HILIC （5μm） 14 x 1 mm PEEK 保护柱（5 件）fitting guard column1.50435.0001ZIC® -HILIC（5μm）20 x 2.1 mm PEEK 保护柱（1 件）fitting guard column1.50436.0001ZIC® -HILIC （5μm）20 x 2.1 mm PEEK 保护柱套件（3 件） fitting guard column1.50439.0001ZIC® -HILIC （3.5μm, 100?） 20 x 2.1 mm PEEK HPLC column1.50440.0001ZIC® -HILIC （3.5μm, 100?） 50 x 2.1 mm PEEK HPLC column1.50441.0001ZIC® -HILIC （3.5μm, 100?） 100 x 2.1 mm PEEK HPLC column1.50442.0001ZIC® -HILIC （3.5μm, 100?） 150 x 2.1 mm PEEK HPLC column1.50444.0001ZIC® -HILIC （3.5μm, 100?） 150 x 4.6 mm PEEK HPLC column1.50443.0001ZIC® -HILIC （3.5μm, 100?） 250 x 2.1 mm PEEK HPLC column1.50445.0001ZIC® -HILIC （3.5μm, 200?） 50 x 2.1 mm PEEK HPLC column1.50446.0001ZIC® -HILIC （3.5μm, 200?） 50 x 4.6 mm PEEK HPLC column1.50447.0001ZIC® -HILIC （3.5μm, 200?） 100 x 2.1 mm PEEK HPLC column1.50448.0001ZIC® -HILIC （3.5μm, 200?） 150 x 2.1 mm PEEK HPLC column1.50449.0001ZIC® -HILIC （3.5μm, 200?） 150 x 4.6 mm PEEK HPLC column1.50450.0001ZIC® -HILIC （5μm, 200?） 50 x 2.1 mm PEEK HPLC column1.50451.0001ZIC® -HILIC （5μm, 200?） 50 x 4.6 mm PEEK HPLC column1.50452.0001ZIC® -HILIC （5μm, 200?） 100 x 2.1 mm PEEK HPLC column1.50453.0001ZIC® -HILIC （5μm, 200?） 100 x 4.6 mm PEEK HPLC column1.50454.0001ZIC® -HILIC （5μm, 200?） 150 x 2.1 mm PEEK HPLC column1.50455.0001ZIC® -HILIC （5μm, 200?） 150 x 4.6 mm PEEK HPLC column1.50457.0001ZIC® -HILIC （5μm, 200?） 250 x 2.1 mm PEEK HPLC column1.50458.0001ZIC® -HILIC （5μm, 200?） 250 x 4.6 mm PEEK HPLC column1.50656.0001SeQuant® ZIC® -cHILIC （3μm,100?） 50 x 2.1 mm PEEK HPLC Column1.50657.0001SeQuant® ZIC® -cHILIC 3μm,100?
