PROCEDURE

NOTE: Before performing the test, it is reccommended that the pump head seals are "exercised" for 30 minutes by preparing the system to achieve a system pressure typically used for the methods run - for example, 10 kpsi. 

1. Ensure that the solvent line is fully submerged in solvent in the solvent reservoir.
2. Open ACQUITY Console.
3. Select the BSM/QSM/ISM from the system tree on the left-hand side of the screen (expand the system tree by clicking the "+" sign if needed).
4. Select "Maintain" from along the top of the window (see Additional Information below)
5. Select "Leak Test" or "Dynamic Leak Test" if available.
6. Keep the default pressure for accumulator and primary unchanged.
7. Select the appropriate pump (if BSM, this will be A or B), solvent line, vent valve position, check Prime and then click "Start".
8. The test runs and displays the test results.
9. Repeat for Pump B (if BSM).
10. If the test fails, prime the system again and run the leak test one more time.
