6.5.3 Seal Conditioning New seals must be conditioned prior to use. Conditioning is the
process of running the seals wet under controlled conditions to
allow surfaces to seat and break-in for proper function of the
seal.
Note
Buffer solutions and salt solutions should never be used to
condition new seals. Recommended solvents are HPLC-grade
methanol or acetonitrile and water
Suggested Conditioning
Parameters Using a suitable column, run the pump with a 50:50 solution of
Methanol/Water for 30 minutes at a flow rate that results in a
pressure of ~1000 psi. Then run the pump for another 15
minutes at a flow rate that results in 3000 psi.
