Mass spectrometry for compounds
1
Q
What is the molecular ion?
A
The parent molecule with just one electron removed, the mass corresponds to the mass of the original molecule, it is just ionized.
2
Q
What other ions reaches the detector?
A
Fragment ions.
3
Q
What is it called when molecules break down into fragments in specific ways?
A
Fragmentation pattern.
4
Q
What is the base peak?
A
The peak of the most abundant ion being set to 100%.
5
Q
Why is there often a small peak just above the molecular ion peak?
A
Due to a small portion of C atoms being C13 isotopes.
