Hello! Our shutdown method that was saved, was over written with our regular acquisition method. What are the suggested instrument parameters for a GC shutdown method? We run an Agilent 6890N with Headspace sampler 7697A using OpenLabs CDS 2.7.

Hi dconner
Before you write a new method, if you have audit trails enabled for methods, you could see what the method parameters were before they were overwritten.
If you can find a datafile that was created using your shutdown method, you could find the acquisition setpoints (method) for that datafile in Data Analysis.

Thank you for the reply. We do not have the audit trail set up (not sure why) but I was able to find Sutdown.amx file before the date it was overwritten. I copied the old shutdown into my methods file on my C: drive but I thought the shutdown had reduced temperatures, shortened time ( tech had it set for about two minutes run on the shutdown), and no ramps but the older one I am looking at still had ramp up etc.
Thank you for any input you can provide.
