Viva Biphenyl 色譜柱（USP L11）

粒徑: 5μm

孔徑: 300Å

碳載量: 6.7%

封端: 有

pH范圍: 2.5 to 8

溫度上限: 80°C

很強的堿基去活化多孔填料，分析廣泛的化合物時都有很好的峰型；是大分子和生物分子分析的理想用柱。對于芳香族和不飽和化合物分析有很高的保留性和選擇性，相對于苯基固定相有更強的保留性。

描述：

·極適用于多肽或蛋白質(zhì)分析

·堅固的球形顆粒，孔徑為300Å

·高的孔隙/表面積比，適用于大分子的分析

Viva色譜柱基于大孔徑填料，我們設(shè)計用來更好的分析大分子物質(zhì)。為了研制Viva硅膠，我們評估了大量的寬孔硅膠。我們發(fā)現(xiàn)盡管很多硅膠很滿足孔徑平均值為300Å 的標(biāo)準(zhǔn)。但是實際上分布在高于或低于這個數(shù)值，150 Å 以下孔徑占較大的比例。這就意味著大部分的表面積對于大分子分析是無效的。Viva柱管的孔徑在這個均值的很小范圍內(nèi)分布，因此在大部分的硅膠表面能起到分離的作用。
