The Backpressure Regulator
A backpressure regulator can be added to the flow path to generate backpressure
and prevent air bubbles from forming in the UV flow cells when medium pressure
columns are used. (The NGC systems ship with a 40 psi backpressure regulator.)
Bio-Rad recommends that the backpressure regulator be plumbed between the
conductivity monitor and the pH monitor to avoid exceeding the 70 psi limit of the
pH probe.
Note:
Bio-Rad does not recommend using backpressure regulators for
columns with a precolumn pressure limit less than 72 psi (0.5 MPa).
