Calculating the Pressure at the Inlet Port of the Flow Cell

Diode Array Detectors (VH-D10)
Operating Manual
6. Calculate the difference between the two measured pressure values:
p5 = p4 – p1.
p5: Backpressure caused by the flow cell
p4: System backpressure with flow cell but without additional
module
p1: Vanquish system backpressure (without flow cell and additional
module)
This procedure describes how to determine the pressure at the flow cell
inlet port (p6) for the intended configuration.
