A mass spectrometer is often linked to a gas chromatograph (GC) so that the
1
Substance can be separated in mass spectrometer and then passed through the GC for analysis
2
Substance can be separated in the GC and then passed through the mass spectrometer for analysis
3
Gas used as the mobile phase in the GC is first purified by the mass spectrometer
4
Exact mass of the mixture is determined by mass spectrometer before it is passed into GC
