Flush LC system pump and line with mobile phase (HPLC grade and miscible with solvents that column is shipped in). Mobile phase starting conditions check list: 1. Ensure that HPLC grade mobile phase is well mixed, filtered, and degassed prior to use. 2. Ensure that column shipping solvent, remaining solvent in LC system, and mobile phase solvents
