?
What are the four stages that occur during mass spectoral analysis
Ionisation, Acceleration, Deflection and Detection
1 of 7
What charge do the ions in the mass spectrometer possess?
Singular Positive Charge
2 of 7
What can occur to the molecules if hit with too much energy?
Fragmentation
3 of 7
What is fragmentation?
When molecular ions are split into smaller parts due to the breaking of a bond, one fragment as a singular positive charge the other is neutral
4 of 7
How can you identify the molecular ion?
It is the peak the furthest to the right, it has the largest mass/charge ratio
5 of 7
What is another name for the tallest peak on a mass spectrometer?
The base peak
6 of 7
How do you represent fragmentation equations?
Molecular Ion (single positive charge) into Fragment ion (single positive charge) + Neutral fragment
