Mass Spectrometry allows you to determine the molecular weight of an unknown compound through its vaporization and ionization. 

Mass Spectrometer

mass spectrometer is used to determine the mass to charge ratio of an unknown compound. 

Concept #1: A mass spectrometer operates under a very high vacuum while the sample is introduced. 

mass spectrometer involves three primary functions: 

1) The vaporization of your unknown compound M into gas M. 

2) The ionization of gas M into the molecular ion or radical cation. 

3) The detection of all gas ion fragments. 

Analysis of all the gaseous ions helps to create a mass spectrum.
