7. When the system pressure has stabilized, read the system pressure
in Chromeleon and write down the value for p1.
p1: Pressure drop at the column, detector inlet capillary and the
waste line
8. Stop the pump flow.

5.7.3 Determining the Backpressure of the Transfer Capillary and the
Additional Module (Without Flow Cell)
This procedure first describes how to measure the backpressure of the
additional module including that of the column, detector inlet capillary
(and waste line) (p2). Afterward, the backpressure of the transfer
capillary and the additional module is calculated (p3) by subtracting the
backpressure of the column, detector inlet capillary (and the waste line)
(p1).
