Hi,

I am using Openchrom to look at my Agilent GCMS data as the instrument is so heavily used there is hardly any time to analyse the data.

I have coeluting peaks which on a SIM method one peak is 70Da and the other is 126Da. I can strip out one of them so that I can integrate the other using Scan Mass Spectrum Filter -> ion remover filter. I can then select the peak and integrate it. However, when I want to do the other peak I cannot find a way to remove the remove ion filter so that I can remove the other ion. Is there a way of resetting the chromatogram back to the start? At the moment I have to close the file (without saving changes) reopen it and then do the other one. It is a pain.

Thanks
