Introduction to the Binary Pump
1
Instrument and Operation
Principle of Operation
The binary pump is based on a two- channel, dual- piston in- series design
which comprises all essential functions that a solvent delivery system has
to fulfill. Metering of solvent and delivery to the high- pressure side are
performed by two pump assemblies which can generate pressure up to
600 bar.
Each channel comprises a pump assembly including pump drive, pump
head, active inlet valve with replaceable cartridge, and outlet valve. The
two channels are fed into a low- volume mixing chamber which is
connected via a restriction capillary coil to a damping unit and a mixer. A
pressure sensor monitors the pump pressure. A purge valve with
integrated PTFE frit is fitted to the pump outlet for convenient priming of
the pumping system.
