ICS-1000 Ion Chromatography System
4-18 Doc. 031879-01 3/03
4.11 No Cell Response
• Cell not properly installed
Verify that the cell front cover is flush against the component panel. If
necessary, tighten the two mounting screws. When the cell is correctly
installed and the screws tightened, an electronics connector on the cell plugs
into a receptacle inside the ICS-1000.
• No flow from pump
This condition has several possible causes. See Section 4.4
and Section 4.5
for details.
• Cell electronics malfunctioning
Use the Chromeleon Wellness Panel diagnostics to test the electronics (see
Section 5.1
and the Chromeleon online Help for instructions). If the variance
reading is outside the tolerance range (less than 1 µS), the electronics are
malfunctioning. Contact Dionex for assistance. The ICS-1000 electronics
cannot be serviced by the user.
4.12 High Cell Output
• Background not suppressed by suppressor
Verify that the suppressor is turned on and the current is set to the correct
value. Refer to the suppressor manual for additional troubleshooting
guidance. Suppressor manuals are included on the Dionex Reference Library
CD-ROM (P/N 053891), located in the ICS-1000 Ship Kit (P/N 057905).
• Sample concentration too high
Dilute the sample Section 3.9.3
.
• Wrong eluent
Check that you are using the correct eluent for your application.
• Background conductivity not offset from conductivity reading
Before making an injection, allow the background conductivity to equilibrate,
and then press
Autozero on the Chromeleon Control Panel.
