Viva C8 色譜柱（USP L7）

粒徑: 5µm, 球形

孔徑: 300Å

碳載量: 5%

端帽: 有

pH 范圍: 2.5 to 8

溫度上限: 80°C

高度堿性去活的寬口徑填料在分析大多數(shù)化合物時均可以產(chǎn)生良好的峰形。進行反相分析時比Viva C18色譜柱的保留值小。

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 的標準。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。
