Hello,
See the attached document. Please note the Chemstation.ini file location is dependent on the installed version. You should find a stub chemstation.ini file in the C:\Windows folder, as below, showing the location of the file. It should be…
Hello, Fast determination of syngas using packed columns and standard gas chromatography in less than 5 minutes or even 2 minutes(!) Is it really possible to achieve? The attached poster might give an idea how to configurate a standard gas chromatograph…
Poster - Fast Standard GC - Determination of Syngas.pdf
Hello,
That looks like a standard IS calibration using area percent. The purity of the standard can be entered as the compound multiplier. I would start by searching the help for calibration, internal standard, and mass percent calculations. You can…
The attached guides provide information about differences in OpenLab CDS for users upgrading from ChemStation or EZChrom.
Change Log:
15Mar2022 Updated EZChrom document to correct a reference.
29Nov2022: Added a note to the ChemStation…
In your method's Windows subdirectory is a file called "acqmeth.txt". Please post that as it contains all of the GC and MS parameters you are using. Also post your latest autotune report.
Residual solvent headspace - is there water in the sample? How…
Hello,
It kind of depends on the version of EZChrom you are migrating from as to the differences you will see as some changes have been made to the EZChrom integrator over the versions. CDS 2.x does contain the EZChrom integrator as a choice in the…
