How do I set solvent delay for GC FID on OpenLab software?

Hi all. I want to set a solvent delay in my GC FID method, similar to how we do it for GCMS. How do I go about it using OpenLab? Thanks.

  • Hi murigi,

     

    I'm going to chime in here with a follow up to James great suggestions.

     

    Usually when customers make this request, it is because they are viewing the full range of the chromatogram and the solvent peak is making it difficult to see their peaks of interest because it has a much greater response. Rather than not collecting data while the solvent elutes, the easiest way to resolve this is (assuming you are using OpenLAB ChemStation) is to choose to Autoscale rather than view the full range. Autoscaling will automatically scale the y-axis of the chromatogram to the second tallest integrated peak rather than to the solvent peak. This option can be found by going to Graphic> Signal Options... as seen below:

     

     

    These scaling options will apply to any chromatograms displayed on classic reports that you print. If you are using intelligent reporting, then you will need to change the chromatogram scaling in the chromatogram properties on the report template:

     

    In the above screenshot, I am choosing to scale to 100% of the 2nd tallest peak in the chromatogram on an intelligent report template.
