Post-Run Activities
After running a method:

Test the changes
•
Remove the used cartridges or disks
•
Prepare to run the next batch of samples
•
Clean up, if done for the day
3.7.1
Determining the Required Changes
Based on the recovery data and operation observations during method
development, you may need to modify the Dionex AutoTrace 280
method. The
Elute Flow
and
Load Flow
parameters are usually the most
critical settings.
For additional assistance, refer to the following sources: the method
development guide published by the manufacturer of your SPE cartridges
or disks, the application tips in
, and the AutoTrace software
Help.
NOTE When attempting to optimize a method, making
changes one at a time is the best way to evaluate the
effect of a change.
