Is it OK to have air bubbles in the seal wash line on an Alliance HPLC system or ACQUITY UPLC system? - WKB109125

Article number: 109125

ENVIRONMENT

  • Alliance HPLC system
  • 2695 Separations Module
  • 2695D Dissolution Separations Module
  • 2795 Separations Module
  • ACQUITY UPLC

ANSWER

Yes. The seal wash is an open system that is not under pressure. The seal wash solvent does not get into the system, so it is acceptable to get some air bubbles in that line. But be sure that there is no leaking from the sides of the pumps, which would indicate incorrect installment of the seal wash tubing back into the pump.
