Welch Materials HPLC Column Ultisi SiO2, 300 Å, 3 μm, 300Å, 4.6 x 250 mm

Ultisil SiO2 column uses ultra-high purity type B silica particles with no metal contents. SiO2 column can separate strong hydrophilic compounds in high concentration organic solvent in reversed phase. Good result can be obtained for the analysis of polar compounds which are prone to peak tailing in reversed phase.
