Ultisil XB-SiO2
– 75 columns
Vendor: 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
