|
relative atomic mass
|
average mass of 1 atom of an element/ 1/12th mass of 1 atom of carbon 12
|
|
|
mass spectrometer
ionisation |
the sample is bombarded with high energy electrons to remove electrons and created positive ions
|
|
|
mass spectrometer
acceleration |
using an electric field, ions are attracted to a negative plate
|
|
|
mass spectrometer
deflection |
using a magnetic field, lighter ions are deflected more
the deflectors field is altered to allow different ions to hit the detector |
|
|
mass spectrometer
detection |
when the inos hit the detector they induce a current which is minitored
|
|
|
Ar (relative atomic mass) from a mass spectrometer
|
relative isotopic abundance x relative isotopic mass / total relative abundance
|
|
|
Mr (relative molecular mass) from a mass spectrometer
|
peak furthest to the right
