Beschreibung
Zusammenfassung:	Time of flight mass spectrometry techniques are simultaneously combined with path-bending spatial dispersion in magnetic- or electric-sector mass spectrometers to improve the mass resolution or, with an ion fragmentation region, to rapidly obtain multidimensional mass spectral data previously only obtainable by tandem mass spectrometry. The instrumentation generates data defining relationships between parent ions and daughter ions produced by fragmentation, metastable or induced, data to differentiate stable from metastable ions, and data to improve mass resolution. The subject time-resolved mass spectrometers can be combined with chromatography apparatus to obtain multidimensional MS/MS-type data during the relatively short duration of a single chromatographic peak.
