Concept explainers

Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Question

Gallium consists of 60. % 69Ga and 40. % 71Ga. Arsenic has only one naturally occurring isotope. Gallium arsenide
is a polymeric material, but its mass spectrum shows fragments with formulas GaAs and GazAs2. What would the
distribution of peaks look like for these two fragments?
