D•FAQ
D.1 How do I connect to an autosampler?
• For instructions on how to connect the ICS-900 to an AS or AS40
autosampler, see the ICS-900 Ion Chromatography System Installation
Instructions (Document No. 065214).
• For instructions on how to connect the ICS-900 to an AS-DV Autosampler,
see the AS-DV Autosampler Operator’s Manual (Document No. 065259).
• For instructions on how to connect the ICS-900 to an AS-HV Autosampler,
see the AS-HV Autosampler Operator’s Manual (Document No. 065125).
All of the above manuals are included on the Dionex Reference Library CD-ROM
(P/N 053891). The ICS-900 installation instructions are also included in the
ICS-900 Ship Kit (P/N 067768).
D.2 How often should I perform calibrations?
Recalibrate every six months or after changing a major component (separator
column, cell, suppressor, etc.).
D.3 Why are the retention times moving?
Retention times can shift if the pump flow is erratic or if the column or eluent is
contaminated. See Section 4.6
for pump flow rate troubleshooting. If a
contaminated column is suspected, clean the column as instructed in the column
manual. Column manuals are included on the Dionex Reference Library CD-
ROM (P/N 053891).
Changes in ambient temperature will have an impact on peak retention times. The
effect varies with the type of column used, but it is generally more pronounced for
certain cation analyses. The magnitude of the effect varies with the analyte and is
proportional to the temperature changes that the column is exposed to.
