1 Introduction
1.1 Instrument description
The 709 IC Pump is a serial dual piston pump especially developed for
ion chromatography and optimized for use with Metrohm ion chroma-
tographic instruments (e.g. 732 IC Detector and 733 IC Separation Cen-
ter). The 709 IC Pump operates with minimal residual pulsation and has
an excellent flow constancy. In addition to the 2.709.0010 Standard
version with parts made of sapphire, ruby, ceramics, Kel-F, Teflon or
stainless steel, the totally metal free 2.709.0110 version is available.
All functions can be set simply at the front of the unit. The current and
entered data are indicated on the LED display. To assure optimum op-
erational reliability, both lower and upper pressure limit values can be
set. If such a limit is reached, the pump switches itself off automatically.
An additional purge valve allows rapid removal of air from the pump
system.
