2.2 Mass Spectrometer

Question 1

what is the use for a mass spectrometer

Answer 1

to find the relative isotopic masses and the relative abundance’s of an isotope in a sample of an element

Question 2

what happens when atoms and injected into the mass spectrum

Answer 2

the atoms VAPORISE, ionised to form +VE (cations) and are accelerated to the same kinetic energy

Question 3

equation for kinetic energy

Answer 3

KE(1/2MV^2)

Question 4

do heavy ions move quicker or slower than lighter ones

Answer 4

the heavier the ion, the sleep it will move, this the ions separate and are detected on a mass spectrum
