Data Acquisition
Data Files
The method can be stored with the result files (run.m). In such cases the
method directory is stored as a subdirectory in the data file directory, using
the option "Save method with Data" in the Run-Time-Checklist.
For data acquired with ChemStation B.02.01 revision and higher, each data
folder (*.D) contains the following two methods folders
• acquisition method (ACQ.M) for each individual data file
• data analysis method (DA.M) for each individual data file
The individual acquisition method ACQ.M is intended to preserve the
acquisition parameters, so it is recommended that you do not change this
method during future data review activities. DA.M is the individual data
analysis method for the specific data file. In the case of, for example,
calibration table updates, the DA.M methods differ for each of the runs. With
ChemStation B.03.01 or higher, this behavior can be switched off by disabling
Unique Folder Creation.
