Explanation
GC/MS/MS makes an effective combination for chemical analysis. Mixture of volatile substances is separated by gas chromatography. Via a transfer line the fractions of each peak are transferred into the ion source where the ionization takes place. After acceleration, the ions pass through a magnetic field which causes deviation of their linear flight curve according to their respective mass. After this magnetic field the detector counts the ions.
