System Pressure Test
If the test fails again, insert the blank nut at the outlet of the previous module
in the stack (e.g. autosampler outlet if TCC has been tested before), and repeat
the test. Exclude each module one by one to determine which module is
leaking.
If the pump is determined to be the source of the leak, run the Pump Leak Rate
Tes t.
NOTE
Often it is only a damaged blank nut itself (poorly shaped from overtightening) that causes
a failure of the test. Before investigating on any other possible sources of failure make sure
that the blank nut you are using is in good condition and properly tightened!
