Varian 4900-CP

[aamorin]

Hello Everyone:
I'm working with a 4-channels portable Varian 4900CP running with Galaxie CDS.
I'm getting a different baseline start in every injection so it's impossible to compare signals of the same injection or the same channel of different injections.
Does anybody knows hoy to set up a timed event to autozero signals at 0.00 min??
Thanks
Alejandro

Check the autozero box in the detector section of the method or on the front panel of the GC (I have a Varian 450, yours might be slightly different).

Hi,
I've just read your mesage and i also have a Varian 4900 CP with the Star chromatography Workstation software.
Do you know how if it is possible to select several chromatograms and expor the peak areas (of all together) to an Excel file.
Thank you in advance.
