Combination of time resolution and mass dispersive techniques in mass spectrometry

Abstract From the Canadian patent

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 the same multidimensional mass spectral data previously obtained 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 ion and data to improve mass resolution. The subject time-resolved mass spectrometers are combined with chromatography apparatus and serve to obtain multidimensional …
