If you're in LC chemstation, I doubt it, because the file menu item "subtract background run", which you could otherwise have used (chemstation doesn't know whether it was really a background) doesn't work with MSD data. However, you could just export the chromatogram to excel and do the job there.

Hold times should be limited to 5 minutes or less if possible. Peaks eluting during the later portion of the hold time may start to broaden, thus making resolution more difficult to achieve. susret sa živim bogom
