Even properly degassed mobile phases may contain some dissolved gases that can release bubbles in the detector flow cell resulting in baseline noise and drift.
The VICI-Jour back-pressure regulator provides a quick and convenient way to improve the stability of detector baseline by providing a constant back-pressure on the flow cell, which stops the release of dissolved gases from the mobile phase.
A spring-loaded diaphragm provides the force that generates the back-pressure.
Spring tension may be adjusted using the back-pressure adjustment screw on the top of the regulator to vary the backpressure without disconnecting any lines.
Because of the unique design, the backpressure regulator has a very small internal volume.
The peak shape is not affected when the regulator is installed between two detectors in a multi-detector system, or between a detector and a fraction collector or fraction collector system.
Typically, 90% or more of a given component's efficiency will be retained upon passing through the regulator.
