Thermal Ionization Mass Spectrometry (TIMS)
Thermal ionization mass spectrometry (TIMS) is designed to obtain high precision isotopic information. Ions are created by passing a current through a thin metal ribbon or ribbons under vacuum. The ions generated are accelerated under vacuum to a magnetic sector where the ions are separated according to their m/z ratio and a detection system.
