Pulse-Dampener: FC4870B Flow Conditioners

PULSE-DAMPENER: FC4870B FLOW CONDITIONER

The Pluse-Dampener is intended for use in Liquid Chromatography applications where continuous post-column derivitization is desired. Installed at the outlet of the pump, the model FC4870B Flow Conditioner provides the pulse-dampening necessary to maintain a smooth baseline. Also the following important features are provided:

• Continuous filtering of the pumped medium
• Working pressure for the reagent pump: check values perform more reliably which results in a more stable flow
• Pressure reading (gauge) for the reagent pump
• Prime/purge valve

The gauge and pressure relief valve assembly consists of a cross for connecting a pressure gauge, an anti-siphon valve and a pre-calibrated relief valve. This is used to indicate post-column pressure and to prevent rupture of the post-column reactor tubing in the event of an overpressure condition. The anti-siphon valve prevents the reservoir gas pressure from pumping reagent while the system is turned off.
