SYMPTOMS

• Sample syringe leak test fails after priming
• No air visible in sample syringe upon priming
• No damage on 2 or 3 port tubing of injector valve

ENVIRONMENT

• ACQUITY UPLC Sample Manager - FTN
• ACQUITY APC Sample Manager - FTN
• ACQUITY Arc Sample Manager FTN-R
• ACQUITY I-Class Sample Manager - Fixed Loop
• ACQUITY I-Class Sample Manager - FTN

CAUSE

The sample syringe plunger seal leaks.

FIX or WORKAROUND

1. Replace the sample syringe (50 µL = 410001348; 100 µL = 700002570; 250 µL = 410001347; 500 µL (HPLC) = 410001647, APC - 100ul 70009529)
2. Verify functionality by performing sample syringe leak test successfully
3. When in use a leaking sample syringe can be inspected to see if solvent present by the plunger.
