module is switched to the next position every 20 min and
conditioned in this way.
5 Condition system "PrepMSM2.smt"
⇒ Rinse IC system with eluent until the desired stability of the
baseline is achieved and the suppressor module is suffi-
ciently conditioned (at least 1 h).
6 Stop system "PrepMSM2.smt"
⇒ Select Stop determination of the Control menu in the system
window. Data recording and time program are stopped, high-
pressure pump and peristaltic pump keep running on.
7 Open and connect system "s-03.smt"
⇒ Select Change of the System menu in the system window.
Select the system file
s-03.smt suited for the METROSEP An-
ion Dual 2 column in the folder
Suppressed and click on
<Open>. The system PrepMSM2.smt is closed, the system
s-03.smt is opened and automatically connected.
8 Start system "s-03.smt"
⇒ Select Start determination of the Control menu in the system
window. High-pressure pump and peristaltic pump are
started, at the same time, a chromatogram window opens
where the baseline is recorded continuously. The status bar
of this window shows the message
Measure(Baseline), beside
this running time, analysis time, absolute conductivity and
number of measuring points per second are displayed. The
messages
Running [761 Compact IC] and Waiting for INJECT
[Suppressed]
appear in the SYSTEM STATE window
⇒ Let the system run for several minutes. If the system has
already been conditioned then a stable conductivity value of
approx. 14 µS/cm will be obtained after a few minutes.
⇒ Double-click the chromatogram or select
View all of the View
menu. The sensitivity is set automatically so that all measur-
ing points are visible.
This function is only available if the integration has been
started. In the present example the integration only starts
after a delay period
Delay = 2.6 min.
⇒ Select the desired sensitivity using the cursor keys <> or
<>. In the chromatogram window the following display is
seen, for example:
