The establishment of EVISA is funded by the EU through
the Fifth Framework Programme (G7RT- CT- 2002- 05112).
Supporters of EVISA includes:
time-of-flight mass spectrometer (TOF-MS)
The TOF MS exploits the fact that ions of different mass-charge need
different times to travel through a certain distance in a field- free
region after they have all been initially given the same kinetic energy or same impulse.
