3 Start system
• Make sure, that the aspirating tubing 63 for the high-pressure
pump is immersed in the eluent.
• Select Startup hardware (Measure baseline) from the Control
menu in the system window. The high-pressure pump is
started, at the same time, a chromatogram window is opened
where the baseline is recorded continuously.
4 Check for leaks
• Check all capillaries and their connections between the high-
pressure pump and the detector block for escaping liquid. If
eluent escapes anywhere then the appropriate compression
fitting must be tightened further or changed.
5 Condition system
• Rinse the system with eluent until the desired stability of the
baseline is reached (normally 30 … 60 min; if the eluent is
changed, the establishment of the ion exchanger equilibrium
on the separating column can take longer).
• The instrument is now ready for sample determinations using
the selected system.
2.10.2 Putting into operation with suppressor module «MSM II»
Before sample solutions can be injected at the versions 2.861.0020
and 2.861.0040 (with suppressor module «MSM II» 46), the entire sys-
tem must be tested for leaks and then conditioned with eluent until the
baseline is stable. At the same time, the suppressor module must be
conditioned. Proceed as follows:
When inserting the column always make sure that it is inserted cor-
rectly in the flow direction shown on the sticker (the arrow must point
in the flow direction).
1 Open and connect system
• Start the «IC Net» PC program, if it has not already been star-
ted (see Section 2.5.3).
• Select File / Open / System in the main window. Open the sys-
tem file created in Section 2.5.4 for the 861 Advanced Com-
pact IC.
