Creating and Modifying Programs
A Program is used to define precisely timed start conditions and Control Commands. Programs are usually created with the Program Wizard and later edited, if necessary, in the PGM Editor (see Control The PGM Editor). In order to be valid, every program must contain the following information:
Signals to be recorded and their parameters
Flow rate and solvent composition (%B, %C, %D - for controlled pumps only)
Inject command
Start of data acquisition (AcqOn)
End of data acquisition (AcqOff)
End of the program (End)
Verify that all relevant parameters are defined in the program. If a parameter is not explicitly defined, Chromeleon will use the setting in the last sequence.
Dionex recommends creating the program automatically (see Automatically Creating a Program), and then editing the file either in the PGM Editor (see Editing PGM Files in the Device Views of the PGM Editor) or manually (see Manually Editing a PGM File in the Commands View).
With respect to GLP (Good Laboratory Practice), Dionex recommends adding comments about all chromatographic settings (e.g., for the column, detector, pump, and the sample components), as well as explanatory notes, at the beginning of the program. However, this is possible only in the Commands view.
