F.1 How do I hook up an autosampler?
For instructions on how to connect the ICS-2000 to an AS or AS50 autosampler,
see
Section B.18 of this manual. To connect an AS40, see Section B.19 . Also refer
to the autosampler operator’s manuals, which are included on the Dionex
Reference Library CD-ROM (P/N 053891).
F.2 How do I print?
Click the Print toolbar button in Chromeleon (see Section 2.2 ).
F.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. The column manual is included on the Dionex Reference Library CD-
ROM (P/N 053891).
F.4 How do I adjust retention times?
Retention times are calculated during calibration. The Use Recently Detected
Retention Time parameter in the Chromeleon QNT Editor ( General tab) can be
used to compensate for some types of retention time drifts; for example,
evaporation of volatile components in pre-mixed solvents or an aging column.
Refer to the Chromeleon online Help or user’s guide for details.
F.5 When should I remake standards?
Standards are used only for calibration and should always be made fresh (they
have a lifetime of only one week).
