Subject: [ABRF Discussion Forum] A negative ion adduct of 100 Da
We are getting a strong and persistent negative ion adduct of 100 Da in
electrospray. We are working with a small molecule (syringic acid). Does
anyone have advice as to the nature and possible origin of the adducting agent?
Any and all advice will be appreciated
