Viva C4 色谱柱（USP L26）-北京明尼克分析仪器设备中心手机版

详细介绍

Viva C4 色谱柱（USP L26）

粒径: 5µm, 球形

孔径: 300Å

碳载量: 3.5%

端帽: 有

pH 范围: 2.5 to 8

温度上限: 80°C

高度碱性去活的宽口径填料在分析大多数化合物时均可以产生良好的峰形。进行反相分析时比Viva C18 或Viva C8色谱柱的保留值小。

类似固定相:BioBasic 4, Symmetry 300 C4, Jupiter 300 C4, Synchropak C4, 208 TP C4

Viva色谱柱基于大孔径填料，我们设计用来更好的分析大分子物质。为了研制Viva硅胶，我们评估了大量的宽孔硅胶。我们发现尽管很多硅胶很满足孔径平均值为300Å 的标准。但是实际上分布在高于或低于这个数值，150 Å 以下孔径占较大的比例。这就意味着大部分的表面积对于大分子分析是无效的。Viva柱管的孔径在这个均值的很小范围内分布，因此在大部分的硅胶表面能起到分离的作用。
