产品简介
    尽管常规填料色谱柱具有优异的选择性和较长的色谱柱寿命,且对于简单的两元流动相(如甲醇/水),当样品为酸性、中性和弱碱性化合物时均可获得较佳的峰不对称度。但当分析药物等样品中的强极性含氮的化合物时,样品峰型就有可能变差,拖尾严重,并导致定量分析精度下降,时常会出现一些小峰埋没于前一拖尾峰的尾巴中,造成该现象的原因是固定相上尚有残余的硅羟基。尽管很多厂家对硅胶表面作了第二次反应,即所谓的“封尾”,以减小残余硅羟基的作用,但往往都不能完全消除残余的硅羟基的影响。Hypersil公司开发的将残余的硅羟基降至极限的Hypersil BDS (Base DeactivedSilica,碱钝化硅胶)系列产品,并用现代衍生反应技术生产出特别适用于碱性化合物的真正均一反相填料。
主要特点
1.碱性化合物有更好的峰型
2.更长的柱寿命
3.更好的稳定性
4.同碱性化合物一样,酸性和中性化合物也有非常优异的峰型—真正的通用柱填料

There has been little movement towards the fiscal and banking unions required to solve the core problems. It remains flawed, with inadequate controls over national budgets and banking systems, and no mechanism to redistribute wealth, particularly between Germany and the peripheral countries.

"Well, we come from San Antonio, Texas, and I ve met a lot of immigrants over the years and nobody s ever told me that they came to the United States looking for the lowest corporate tax rate," Castro zinged.
