Ultisil XB-SiO2

by Welch Materials

Ultisil XB-Silica columns is applied with ultra high purity (>99.999%) type B silica particles, and there is no metal contents in the column. Just like the XB-CN column, the XB-SiO₂ column can be use in the normal and reverse phase. We could get good result for the analysis of polar compounds which always leads to peak tailing.

Ultra high purity silica (>99.999%)
Smoothpak proprietary surface modiﬁcation to ensure less acidic and uniform surface silanols
