Adduct in GC-MS?
Posted: Sun Dec 12, 2004 11:37 am
have anyone ever heard that GC-MS with electron impact could generate adducts? more exacly proton adducts.
I´m performing a TMS derivative analysis and some of my peaks are giving 1 mass unit higher than literature, even standards.
other people insist that the equipment is calibrated.
thank you
