Thermo Scientific Hypersil BDS色谱柱

碱性去活硅胶，更好的重现性和色谱峰对称性

Thermo Scientific Hypersil BDS 色谱柱自 1989 年发明以来，一直广受业界推崇，被认为是、重现性、最可信赖的色谱柱之一。Hypersil BDS 色谱柱以高度碱性去活硅胶为担体，采用封端技术屏蔽硅醇基，具有以下优点：

 出色的重现性

 明显改善峰拖尾

 十分耐用，色谱柱使用寿命较长

 不论是碱性化合物还是酸性化合物，均呈现峰形。

为什么要用碱性去活硅胶和键合相？

使用共价键合硅胶固定相，可对多数化合物进行分离。HPLC 与液-液分配色谱相比，具有平衡速度快、分配性能更好的特点，因此，HPLC 作为现代分析手段被广泛应用。

但是，传统的共价键合硅胶固定相存在以下问题：

HPLC 中使用的建和硅胶固定相与分析物之间存在多种相互作用，这些相互作用一部分是键合相本身与分析物之间的作用，另一部分是键合时在硅胶表面残留的硅醇基与分析物之间的作用。

硅醇基的数目和酸性极大程度影响了它与分析物间相互作用的强弱。碱性硅胶的酸-碱相互作用主要是由硅醇基产生的，硅醇基还决定了硅胶填料的表面极性。硅醇基的种类和酸性在很大程度上影响了 HPLC 的分离度和分析物的色谱峰形。

残余硅醇基与化合物的相互作用会使酸性和碱性化合物的色谱峰产生拖尾。早期使用的 HPLC 硅胶填料，硅醇基具有很强的酸性，因此色谱拖尾现象特别明显。

使用早期硅胶填料时，若要得到较好的色谱峰，通常需要在流动相中添加酸（醋酸）或碱（三乙胺），使其与硅醇基产生竞争性结合，从而改善色谱峰形。当使用了合适的流动相添加剂时，色谱峰形会得到明显改善。通常需要很高的添加剂浓度——多数情况下达到 1% （体积比）或更高，这样才能使所有残留硅醇基都与添加剂结合，而不影响分析物的色谱峰形。但是高浓度添加剂常常严重降低色谱柱寿命和方法重现性。

所以Hypersil BDS 是的碱性去活硅胶之一，具有以下优点：

减弱硅醇基相互作用

改善色谱峰拖尾

不需向流动相中加入添加剂

的色谱峰对称性

延长色谱柱使用寿命

提高柱效（分析碱性、酸性、中性化合物）

Hypersil BDS重现性，批次间测试流程，多种固定相：

Hypersil BDS 色谱柱是根据标准生产的，并进过严苛的质量控制。硅胶担体和色谱柱的生产流程均*遵守 ISO9001:2000 标准。在进行键合前，BDS 硅胶必须通过 30 余项物理特性和色谱性能测试。在键合后，所有的 BDS C18 填料都经过色谱性能测试以及碳载量测试——该测试在封端前和封端后各进行一次。

Hypersil BDS 色谱柱有 4 种键合相供选择。所有 Hypersil BDS 色谱柱，均使用碱性去活工艺处理硅胶担体，再经封端处理屏蔽硅醇基，即使是分析碱性化合物，也极大程度改善了峰拖尾。每支 Hypersil BDS 色谱柱都带有《质量认证书》
