What are the reasons for the lower sensitivity of ESI-Quadrupol instruments
in negative ion mode? From a naive point of view it is only a change in the
polarities of the different voltages which should not influence the
sensitivity.
Can someone give me a physical explanation or point me to a reference?
Best regards
Peter
