Method Parameter Settings
Signal Polarity
Use this item to set the polarity of the RID signal. Because of
the nature of analytes and eluents, refractive index detectors
can show negative and positive peaks, even within a run.
Automatic Zero Before Analysis
Use this setting to activate an automatic zeroing of the signal
before the run is started. If automatic purge is selected, the
purge will be performed before the automatic zero.
Automatic Recycling After Analysis:
This parameter can be used to select between automatic
recycling of the effluent (On) or directing the effluent to the
waste outlet of the RID (Off) after the run.
Automatic Purge
This parameter can be used to purge the reference cell and
wait additional time for baseline stabilization. It is initiated
each time the run is started. This should be used only if the
content of the reference cell is expected to degrade during a
run. The automatic purge is completed before the autozero is
performed and before the injection is done.
Timetable
You may set up time events to change functions with their
parameters over the run time. Add lines as required.
Time Limits: 0.00 to 99999.00 min in steps of 0.01 min.
Via the buttons in the bottom area time table lines can be
added, removed, cut copied, pasted or completely cleared.
Based on the chosen function, a certain parameter can be
selected.
