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
precalibrated 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.

FLOW RESTRICTORS
Pickering restrictors are tubes packed
with sized diamond particles designed
to provide a desired back-pressure,
relative to a given flow rate and
viscosity. The restrictor tube and
fittings are type 316 stainless steel
or PEEK. The diamond packing is
chemically and chromatographically
inert to all mobile phases.
Features include:
• Pressure-calibrated to flow rate and
viscosity
• Diamond-packed tubes with nuts and
ferrules
• Improve pump efficiency
• Essential pulse-dampening component
• Trouble shooting aid for HPLC
systems
