Im currently trying to run a calibration of an aqueous peptide sample on our Waters triple quad lc-ms, but I'm finding that when I run the same sample in duplicate, the background noise is changing a lot between runs and so the peak area is drastically changing too. Does anyone have any ideas why this may be? My run has fairly long wash/equilibrate steps built in.
Thanks!
