The possible causes are:
• Septum of the System integrity tool must be replaced.
• Syringe (barrel and plunger) must be replaced.
Solution:
• Press RETRY to re-execute the test;
• Press CONTINUE, to go on with the run, even if the test has failed.
• Press ABORT to stop the run and solve the problem.
To solve the problem, the first operation that must be carried out is the replacement of the septum
of the System integrity tool (see paragraph 3.6.3 “System integrity tool installation”) for the septum
replacing instructions.
After the septum change, re-execute the test.
If the System integrity test fails again, press ABORT one more and replace the syringe. Replace
both the syringe barrel and plunger (see paragraph 9.1.5 “Syringe replacement in the syringe
warmer assembly”). Re-execute the run.
8.15 Damage to syringe needle
Damaged syringe needles are normally caused by using incorrect vials, syringes or injection
septum; they can also be caused by the incorrect syringe installation/configuration.
It is recommended to:
Try to identify the cause of the damage and the position in which the damage happened. Ensure
the alignment on the sample vials and on the injector(s) (see paragraphs 4.2.1 “Setup: Alignment”)
were made correctly. Check that the septa of the sample vials and injector are correctly pierced in
the centre.
Check that the syringe was installed correctly, as indicated in paragraph 4.2.2 “Setup: Syringe
warmer assembly installation”, and ensure that all instructions and notes were followed. In
particular, check that the vial locator was correctly aligned with the needle tip, as indicated in the
following figure:
