Ultiate XB-CN(氰基)液相分析柱
Ultiate XB-CN色譜柱有正相和反相兩種模式。反相氰基柱對疏水性分子洗脫快,對極性化合物具有*的選擇性,對強(qiáng)堿性化合物分離具有良好的峰形,與C18、C8等反相柱具有不同的選擇性。在所有反相色譜柱中,極性zui強(qiáng)。在疏水性十分強(qiáng)的化合物用標(biāo)準(zhǔn)C18和C8柱和典型的反相洗脫液不能洗脫時,可用氰基柱。
在正相色譜中氰基柱可以替代硅膠柱。鍵合正相柱有快速平衡和比非衍生硅膠表面活性更*的特點。為延長色譜柱的壽命,交替調(diào)換正相反相的洗脫機(jī)是應(yīng)該避免的。
- 在正相和反相中都可以得到應(yīng)用
- 穩(wěn)定的高覆蓋率鍵合相
- 較低的疏水性,具有*的選擇性
