Waters Corp XTerra MS C18 Prep Guard Cartridge, 125Å, 5 µm, 10 mm X 10 mm, 1/pk
XTerra Prep columns bring the benefits of Hybrid Particle Technology to isolation and purification applications in discovery and development laboratories. XTerra Prep MS columns possess our patented Hybrid Particle Technology, with particles engineered specifically for prep. It allows you to routinely operate at pH 1-12 so you can load up to 60X more onto the column. More capacity results in fewer injections for the same amount of pure material or more material with the same number of injections. In the discovery world, this greater capacity means you can use a shorter column, producing the same amount of material in half the time.
