GCxGC-TOFMS GACID Inlet Separation Identification Identification by TOFMS Full mass spectrum with every extraction pulse firing without necessity of scanning the entire mass range Repetition rates up to 100kHz achievable, which allows monitoring fast sample composition changes on time scales much smaller than milliseconds High initial energy spread of ions up to several hundred eV is admissible Neither static nor dynamic magnetic fields are required Performance depends mainly on electrical circuits rather than mechanical alignment Mass scale calibration for TOFMS is simple and reliable 09/23/2005 S.
