Positioning the Modules
Before putting each module in position, make sure
that each module is ready, i.e. that the fuses have
been installed and that any mechanical installation
is finished.
The physical positioning of each of the modules in
your system will depend on your type of system.
Some suggested layouts are given below. These
layouts have been desigend to make the hydraulic
and electrical connections as simple as possible.
Manual Injection System
This is a binary gradient system with two pumps,
one manometric module, one mixer and one
detector. The pumping system consists of one 305
Master pump and one 306 slave pump. The different
modules should be located as shown in the figure
opposite.
The detector is located at the bottom of the stack and
the pumps and other modules are positioned over it.
The 305 Master pump should be the top pump. This
makes the hydraulic connections to the manometric
module as short as possible which gives the best
results. It is also easy to read the display and to use
the keypad.
Auto-Analytical System
This is a binary gradient system with two pumps,
one manometric module, one mixer, one detector
and one auto-sampler.
The pumping system consists of one 305 Master
pump and one 306 slave pump. The 305 Master
pump should be the top pump. This makes the
hydraulic connections to the manometric module as
short as possible which gives the best results. It is
also easy to read the display and to use the keypad.
The figure opposite shows the layout with a Gilson
231-402 auto-sampler. The next figure shows the
layout with a Gilson 232-402 auto-sampler.
