Setting Up a Method using Edit Entire Method
Data Analysis
Signal Details
The
Signal Details
screen can also be directly accessed in
Method and Run
Control
view: right- click on the graphical user interface on the
Calibration
icon, and then select
Signal Details
in the context menu. In the Data
Analysis view, it can be accessed through the menu
Calibration > Signal
Details
.
The
Signal Details
screen is the next step in
Edit Entire Method
and it tells
Data Analysis which of the acquired signals to process. The drop- down
box lists the available signals, including the analytical signals defined in
the detector settings, and recorded parameters such as temperature, flow,
composition, pressure and diagnostic traces. Select a signal and click
Add
to Method
to transfer it to the
Signal Details
table shown in the lower part of
the screen. You can select any or all of the acquired detector signals for
processing. If no signals are selected, the table is empty; in this situation,
ChemStation will default to processing all of the acquired detector signals.
Sometimes the user might edit an existing method to create a new method
and is faced with a
Parameter Mismatch
error when attempting to run the
method. What has happened is that in the old method the
Signal Details
contained a specified signal, for example 250 nm with 8 nm bandwidth,
and this is changed in the new method to 254 nm/12 nm for example. The
Signal Details
table still contains the original details and is being told to
process a signal which is no longer acquired. Highlighting the old signal in
the table and using the
Delete Row
button will correct the problem.
If a system uses multiple detectors such as the diode- array detector and a
mass spectrometer, the
Signal Description
lines allow delay times for the
downstream detector to be entered so that the software can align the
peaks from the different detectors.
