Static leak test
The static leak test performs a solvent pressure ramp up, and monitors the
pressure decay in the solvent delivery system to determine whether the inlet
check valves, tubing, fittings, or plunger seals are faulty.
Perform the Static Leak test when these conditions apply:
• You suspect leakage in the inlet check valves or plunger seals.
• You performed maintenance on the solvent management system.
• You replaced fittings in the flow path.
Required materials
•Pin plug
• Wrenches, 5/16-inch, open-end, two
• Wrench, 5/8-inch, open-end
• Waste container
To ensure a successful static leak test, precondition the solvent management
system.
To precondition the solvent management system:
1. Ensure that the solvent line that you choose for the static leak test is in
100% methanol.
2. Place a restrictor at the in-line filter outlet to produce 27579 kPa (275.8
bar, 4000 psi) at a flow rate of 1.0 to 1.5 mL/min. for 10 minutes.
Requirement: Keep the in-line degasser in On mode throughout the
preconditioning phase.
Miscellaneous Door Open The sample compartment door is open.
