If you change the eluent type, particularly when changing from a
strong to a weak eluent, then it may take longer to equilibrate the
suppressor.
5 The system is now ready to carry out an analysis
Stop sequence
1 Switch off pump
Step 2 is only necessary when the suppressor will not be used for
more than one week; otherwise continue with step 3.
2 Rinse suppressor
• Leave the suppressor switched on and rinse it with pure water
for 15 min (1 mL/min).
3 Switch off suppressor
• Switch off the suppressor at mains switch 16.
You can also leave the 828 IC Dual Suppressor switched on when it is
not being used; this will not damage the instrument. However, when it
is switched on the vacuum pump operates continuously. This is why
we recommend that the 828 IC Dual Suppressor is always switched
off when it is not being used in order not to unnecessarily shorten the
working lives of the vacuum pump and CO
2
absorber cartridge.
You should also seal the inlet of the CO
2
absorber cartridge when the
828 IC Dual Suppressor is not to be used for a longer period.
4 Storage
These measures are only necessary when the IC Dual Suppressor
will not be used for a long time.
• Remove the connections from the following inlets and outlets:
"To Detector" 7, "From Column" 8 and "To Waste" 12 and
seal them with the original closures supplied with the
instrument.
3.6.2 Software control
The operation and functions of the two control programs IC Net 2.1
and 761 PC Software 1.1 are identical in many respects. Where
differences occur these are described separately for the particular
software.
