Fields used in OpenLab CDS

It depends on the acquisition software which values are available in the ACAML file that Data Analysis evaluates. Values that are processed only by OpenLab ChemStation or OpenLab EZChrom will be displayed in Data Analysis after loading the original data. However, after processing data in Data Analysis, these values will be empty as they are not recalculated.

x = the value is calculated

n/a = the value is not calculated

Parameters in the Custom Calculation Editor may use slightly different names. In the Custom calculation parameter column, x means that the same name is used as in the Report Template Editor. If a different name is used, the correct name is listed.

 

If you installed an OpenLab CDS Add-on, more values are available. See Dictionary of fields used in 2D-LC or Dictionary of fields used in Library Manager for details.
