2.3 Sample Loading Modes
The AS-HV supports two sample loading modes:
•
In the push mode, sample enters the sample loading pump and is then pushed
into the sample loop or concentrator column.
•
In the pull mode, sample is pulled into the sample loop or concentrator
column via the sample loading pump.
The sample loading mode is determined by the components that are installed and
the plumbing connections; for schematics showing typical configurations, refer to
Appendix B .
Sample Overlap
To reduce the time between injections, some Dionex devices, including the AS-
HV, support overlapping sample preparation. This means that, while data
collection and analysis for the current sample are still in progress, the AS-HV can
perform sample preparation steps for the next sample. When the autosampler
finishes the overlapped functions, the Chromeleon program waits, if necessary, to
finish the currently running sample. Then, the remaining commands in the
overlapped sample's program are executed.
Sample overlap is enabled in the Chromeleon Program Wizard (see Section 3.2.4 ).
Pour maintenir la protection contre les risques d'incendie ou
d'électrocution, remplacez toujours les fusibles par des fusibles du
même type et du même calibre.
Zum Schutz vor Feuer und Stromschlägen müssen beim
Sicherungswechsel immer Sicherungen des gleichen Typs und mit
gleicher Leistung verwendet werden.
