Fluctuations in HPLC pump pressure can commonly be attributed to air bubbles in the mobile phase line. Ensuring that all fittings are secured properly, verifying flow rates, and priming the system to remove air bubbles are essential steps. If issues persist, cleaning or replacing check valves and pistons as per the manufacturer's guidelines is recommended. Preventive maintenance, such as filtering solvents and regular system checks, along with the use of a back pressure regulator, can also help stabilize pump pressure and prevent fluctuations.
