严格碱去活键合相,疏水长链内键和极性基团。独特的选择性和高度碱去活能降低或消除流动相添加剂的使用奥特IBD (intrinsically base deactivated) 柱 可以说是功能最全面的色谱柱。它能同时分析酸性,碱性和中性化合物的混合物,而且峰形不会拖尾。其在它的固定相烷基链中含有一个极性官能团, 这个官能团对化合物的分离及色谱保留都会起作用。此官能团可以与硅胶表面的羟基相互作用,使得奥特IBD色谱柱在末端未封闭的情况下,也可以消除色谱峰拖尾现象,并可以同时分析酸性、碱性、两性及其他极性混合物。
奥特IBD 柱分析碱性化合物时在不需要加入调节剂的情况下,色谱峰形依然很尖锐,这也是奥特IBD 柱用于LC/MS 分析的一个很大优势。
奥特IBD 柱同样适合分析酸性化合物。这种色谱柱的固定相兼有极性和非极性的特点。所以奥特IBD 柱的应用方式有两种(正相和反相)(Figure 2); 当分析酸性化合物时,一般采用反相分离模式,这样固定相中的极性官能团可以与酸性化合物相互作用,增加其保留能力。
奥特IBD色谱柱对亲水性化合物的保留能力很好,这是普通C18的一个很好的补充。
与其他色谱柱比较的特点是:
虽然末端没有封闭,由于采用了先进的键合技术,色谱峰形依然尖锐、对称专为同时分析极性与非极性混合物设计
