Description
GC/MSD makes an effective combination for chemical analysis. Mixtures of volatile substances are separated by gas chromatograph. 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. -
