Mass spectrometry is a vital analytical method that allows for the precise examination of organic compounds through ionization and fragmentation. The methodology includes the use of a mass analyzer to separate ions based on their mass-to-charge ratio, enabling a detailed analysis of the components in a sample. This chapter discusses key aspects of gas chromatography coupled with mass spectrometry (GC-MS), including the functionality of mass analyzers, data processing for compound identification, and quantification techniques.
