In order to operate a 2-channel Separation Center with chemical sup-
pression a 2.833.0020 IC Liquid Handling Suppressor Unit is addition-
ally required. For this reason the 1.753.0100 Suppressor Module of the
833 IC Liquid Handling Suppressor Unit is placed on the floor of the in-
ner compartment of the Separation Center (see Fig. 25).
In a 2-channel system with suppressor module the first IC separating
column, just like in a 1-channel system, is connected on the left-hand
side to injection valve A and detector block A (similar to Section 2.9.5,
Fig. 21). Components of this channel are shown in dark gray in Fig. 25.
The second column, just like in a 1-channel system with suppressor
module (see Section 2.9.7 and Fig. 23), is connected on the right-hand
side to injection valve B and detector block B. The installation of the 833
IC Liquid Handling Suppressor Unit is described in the 833 Instructions
for Use; connection to the 2.820.0X20 Separation Center is described
there in detail in Section 5. Components of this channel are shown in
light gray in Fig. 25.
2.9.9 Leak testing and conditioning
Before sample solutions can be injected in the IC system, the entire
system must be tested for leaks and then conditioned with eluent until
the baseline is stable. Proceed as follows:
1 Switch on instruments
• Switch on 818 IC Pump at mains switch.
• Switch on 819 IC Detector at mains switch 2.
• The 820 IC Separation Center is normally supplied via
the 819 IC Detector, see also Section 2.4.2.
• If present, switch on 833 IC Liquid Handling Pump Unit at the
mains switch.
• If present, switch on 830 IC Interface at the mains switch.
• Switch on PC and start «IC Net», load a system correspond-
ing to the device configuration or create a new one (see «IC
Net» Instructions for Use).
• Start the system with Control/Startup hardware . The 818 IC
Pump and, if present, the 833 IC Liquid Handling Unit will
start to run, and the baseline will be shown in the chroma-
togram window.
