How does the ABPR diagnostic confirm the integrity and readiness of the ACQUITY UPC2 System fluidics? - WKB21193

ENVIRONMENT

• ACQUITY UPC2 System
• ACQUITY UPC2 Binary Solvent Manager (ccBSM)
• ACQUITY UPC2 Convergence Manager (cCM)

ANSWER

ABPR (Active Back Pressure Regulator) diagnostic is performed to confirm the integrity and readiness of the system fluidics.

• ABPR Minimum Pressure Test is 900-1,400 psi (ideally 1,000-1,100 psi).
  • The 0% (static) portion of the test tells you if your static cartridge is functioning properly.
  • Pressure must be above 1000 psi, preferably above 1100 psi, when running at 1 mL/min CO₂.
• ABPR Power Test is 3,000 - 5,000 psi (ideally ~4,500 psi).
  • The 45% (dynamic) power test is the true leak test.
  • The system must be able to maintain a pressure above 3000 psi for two minutes when at 45% power (ideally, this value should be about 4500 psi).
