10 Purification Solution - Developer's Guide

Preparing Default Purification Methods
In This Book
It is highly recommended that the pumps are not switched off in a pre- or post-run 
command of the method.
Methods rely on the instrument configuration and driver revision. If you change the 
instrument configuration or upgrade the driver revision for which you originally set up your 
purification (base) method, you must at least save the method for the changed instrument 
configuration under a new name. However, we recommend that, for a changed instrument 
configuration or upgraded driver revision, you create a new method from scratch. 
Otherwise, method resolution will try to adapt the methods from the old 
configuration/driver revision with every method load (that is, for every sample run), 
leading to a method changed state, and preventing the run going forward.
When creating a new task based on a task template with a different instrument 
configuration, make sure that you choose an appropriate preparative base method for the 
current instrument configuration and driver revision.
We recommend that you choose different task root folders for different instrument 
configurations so that you do not mix different configurations in the same task root folder.
