2 Installation
792 Basic IC
42
4 Check for leaks
x
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 fitting
must be tightened further or changed.
5 Condition system
x
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).
x
The instrument is now ready for sample determinations using
the selected system.
2.9.2 Putting into operation with suppressor
Before sample solutions can be injected at the 792 Basic IC (with use
of the 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 "
x
Start the
