  • I recall facing a similar issue a while back. Waters had to come in and replace some parts in the UPLC. I don't remember the specifics. You pretty much narrowed it down to the instrument by replacing the LACE and cables.
  • Please check the Acquity ICOP is above DP4 SR1 or the latest one DP2017 R1 installed .
    Secondly ensure the network speed is good from Lac/e to the Servers and no packet drops.
  • DP2017 R1  will resolved all these issues, make sure instrument firmware also get updated.
