have sufficient volatility. The theory behind the mass spectrometer is to use the difference in mass-to-charge ratio (m/e) of ionized atoms or molecules to separate them from each other. Mass spectrometry is therefore useful for quantitation of atoms or molecules and also for determining chemical and structural information about molecules. Molecules have distinctive fragmentation patterns that provide structural information to identify structural components. The combination of the gas chromatograph and mass spectrometer is very easy, because both instrument needs to be modified in excess and both are analyzed in the gas phase and have comparable sample levels and temperature ranges. The ! most important feature of the tw o instruments being coupled is that they perform complementary analytical functions.
The instrumentation of the gas chromatograph/mass spectrometer is very complex. The instrument's parts include an injector, a carrier gas, a column, a separator, an ionization ...
