5.8.2 Measuring the Vanquish System Backpressure (Without Flow Cell and

Additional Module)

Page 74
7. When the system pressure has stabilized, read the system pressure
and write down the value for p0.
p0: Backpressure caused by the waste line
8. Remove the waste line from the pump/static mixer outlet port.
9. Connect the autosampler inlet capillary to the pump/static mixer
outlet port.
This procedure describes how to measure the Vanquish system
backpressure including, for example, the autosampler inlet capillary, the
column inlet capillary, the column, detector inlet capillary or detector
inlet capillary with overpressure relief valve, and the waste line (p1).
