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, the appropriate compression fit-
ting 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.
2.9.2 Putting into operation with suppressor (anion system)
Before sample solutions can be injected at the 2.790.0020 Personal
IC (with suppressor), the entire system 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:
1 Open system " Prep MSM.smt"
• Start the «790 Personal IC» PC program, if it has not already
been started (see section 2.5.3).
• Select File / Open / System in the main window. Open the folder
790com1 or 790com2 and select the system file Prep MSM.smt .
Click on <Open> .
2 Open control window
• Double-click the 790 icon in the system window. The control
window for manual control of the 790 Personal IC appears,
which indicates conductivity, pressure and current system
parameters.
