As a workhorse for HPLC method development, XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1-12). The trifunctionally bonded C18 ligand provides you with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability, and ultra-low column bleed.. In some cases, the column label indicates "XBridge C18", while the Waters website lists the more descriptive name "XBridge BEH C18". The two names apply to the same particle design. XBridge = HPLC column version of the BEH particle: available in 2.5um, 3.5um, 5um particle size. BEH = The general particle technology.
The XBridge Premier Peptide BEH C18 Column, 300 Å, 2.5 µm, 4.6 mm X 50 mm Columns have been specially optimized and QC tested with cytochrome c digest standards (p/n: 186006371) for peptide separations. The wide-pore (300Å) trifunctionally bonded BEH particle offers the widest usable pH range, superior low pH stability, and ultra-low column bleed to assay samples for especially large.. XBridge HPLC and UHPLC Columns are available in a broad range of sorbent particles and sizes: XBridge eXtended Perfomance (XP) 2.5 µm Columns for rapid analytical UHPLC separations; 3.5 and 5 µm HPLC columns for reliable analytical method development; and 5 and 10 µm optimum bed density (OBD) preparative columns for purification chromatography.
