Evaluating The Results - Agilent Technologies 1260 Infinity User Manual

Evaluating the Results

The sum of all leaks between the pump and the blank nut will be indicated by a
pressure drop of >2 bar/minute at the plateau. Note that small leaks may cause
the test to fail, but solvent may not be seen leaking from a module.
Please notice the difference between an error in the test and a failure of the test! An error
N O T E
means that during the operation of the test there was an abnormal termination. If a test
failed, this means that the results of the test where not within the specified limits.
Often it is only a damaged blank nut itself (poorly shaped from overtightening) that causes
N O T E
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!
