Salt buildup can affect performance and increase maintenance costs.

This TECH TIP can help alleviate the problem – and reduce service calls:

When using buffers such as phosphate salts in your HPLC solvents, at the end of a sequence run HPLC grade water 100% as a solvent at 1 ml/min for 60 minutes to remove buildup of the salts. Running a 100% water method at the end of a sequence will keep the seals and pistons from premature failure or restricting the rotors/tubing in the HPLC system.
