It will fit into your XBridge BEH Shield RP18 Column with ease and save you the costly time and resources wasted on frequently replacing liquid chromatography columns.

FAQ
How do I equilibrate my Xbridge Column? Xbridge columns come shipped in 100% acetonitrile, so it is critical to ensure that your mobile phase is compatible before switching to a different system. Equilibrate your column with more than ten column volumes of mobile phase. Flush the column with five column volumes of or organic solvent mixture.
