Question 1

mass spectrometer regions

Answer 1

Sample inlet > ionization chamber > ion acceleration region > drift zone> ion-detector

Question 2

What does “m/z” mean on x-axis of percentage abundance (y-axis) graph

Answer 2

m/z = mass/ charge ratio

Question 3

Ar =
(75.78% of 35)
(24.22% of 37)

Answer 3

(relative atomic mass)
Ar = (percentage abundance * relative isotopic mass)/ percentage abundance
e.g Ar = (75.78*35) + (24.22 * 37)/100
Ar = 35.48
