Vaporisation
sample is
vaporised
Ionisation
sample is bombarded with
high
energy
electrons
which ionises the atom to form
+1
charge
Acceleration
positive ions passed through
electric
field
particles with lower
m
/
z
ratio will accel
quicker
detection
ions are detected as
electrical
current
is made when
particle
hits the
plate
