3.3 Base tray and bottle holder
3.3.1 Basic information on base tray and bottle holder
The base tray (6.2061.110) and bottle holder (6.2061.100) protect IC
instruments from dust, dirt and leaking fluids. The supply bottles for eluent
and auxiliary solutions can be positioned neatly on the bottle holder.
In a complex IC system, several different instruments may be used, such as
an analyzer, an extension module and a detector. These instruments can
be set up in one or more stacks. We recommend that a base tray and bot-
tle holder be mounted for each stack of IC instruments.
The bottle holder and base tray must be removed or set up every time one
of the following instruments is to be mounted on or under a 940 Profes-
sional IC Vario:
￭ One or more 942 Extension Module Vario.
￭ Or another instrument with the same-sized footprint.
3.3.2 Mounting base tray and bottle holder (optional)
The base tray and bottle holder come fully assembled on a new ion chro-
matograph. If you wished to install an extension module on the ion chro-
matograph, you would have to remove the bottle holder and put it back
on top of the topmost instrument. If you wished to install an extension
module below the ion chromatograph, you would have to remove the
base tray and set it under the lowest instrument.
3.3.2.1 Removing/mounting the base tray
The base tray must be removed if you want to install another instrument
under the IC instrument.
CAUTION
Do not allow capillaries or leak sensor cables to be pinched!
Pinches in the leak sensor cable or the capillaries fed through the guide
ducts between the base tray and the instrument may lead to malfunc-
tions.
Unplug the leak sensor cable. Remove all of the capillaries from the
capillary ducts.
