HPLC Backpressure Regulators

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. VICI-Jour back pressure regulators provide 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.

Because of their unique design, VICI-Jour back pressure regulators have 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.

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 back pressure without disconnecting any lines.
