These peaks are gigantic! The top chromatogram shows peaks 100 million counts tall? The bottom one shows peaks 10 Million counts tall. The baseline in the bottom one is a million counts? That baseline should be maybe five to ten thousand counts or less.
Have you performed normal inlet maintenance including replacing the inlet septum, don't overtighten it, liner, O ring, cleaning the MMI or SSl replacing the gold seal, and trimming maybe 30cm or more off the front end of the column, then reinstalling the column 12-15 millimeters above the ferrule? How old is the column? How long since the full preventive maintenance has been done on this system? Has the inlet split vent trap been replaced lately?
You need the smallest peak in your lowest concentration standard to be down around 3x to 5x the background noise. You should be injecting the smallest amount of the lowest concentration of the cleanest sample possible to minimize system maintenance.
