Chromatography Forum

Hello All,

I am new to using the Saturn 2000. I am trying to pick a point on the chromatogram to be the "apex" for a spectrum. I have a peak that is far too large and the library search is choosing the wrong compound. The library search is successful if I select the spectrum to the left of the apex.

My question is, how do I make it the spectrum to use for the report. I am able to move the peak start and end points but I'm not able to select a point on the peak to select the spectra I would like. Any help would be greatly appreciated.

Regards,

John

Hi John

I think this can be done in the compound table...select the part of the peak you want to use as the reference spectrum and update the retention time. Then go to the reference spectum tab and use the "put sample in ref" to update the spectrum. This should use the part of the spectrum you selected at that RT

Hope it works for you.

Regards
