Web• Use low protein-binding microcentrifuge tubes to ensure maximum sample recovery. • Store high-pH buffers in polypropylene tubes at room temperature. Do not store high-pH buffers in glass vessels. • Avoid sample contamination and direct skin contact with solvents and chemicals. Always wear gloves when handling the spin columns and samples. WebSep 9, 2024 · In this study, a “salt-free” high-pH RPLC was evaluated as an orthogonal dimension of separation to conventional low-pH RPLC with top-down MS. The RPLC separations with low-pH conditions (pH=2) and high-pH conditions (pH=10) were compared to confirm the good orthogonality between high-pH and low-pH RPLC’s.
