mass spectrometry Flashcards
1
Q
define base peak
A
peak of greatest abundance in the mass specrum
2
Q
molecular ion peak
A
a peak produced by an ion formed by the removal of one electron from a molecule
3
Q
m+1 peak
A
a peak produced by a molecular ion with an increased mass due to the presence of one carbon-13 atom
4
Q
fragmentation ion
A
a positively charged ion produced when the molecular ion breaks apart
