Title:
MASS SPECTROMETER AND METHOD OF MASS SPECTROMETRY
Document Type and Number:
WIPO Patent Application WO/2010/044370
Kind Code:
A1
Abstract:
Connection of a high-speed analyzer such as a quadrupole mass filter with an analyzer which, in contrast to the high-speed analyzer, necessitates a reaction time of 10 msec, such as an ion dissociation chamber of the ion trap type, has a problem that an ion loss occurs due to a difference in analysis speed between the analyzers. This loss is eliminated to render high-throughput analysis possible. A precursor ion trap (4) is disposed between a quadrupole filter (3) and an ion dissociation chamber (5) to accumulate ions in the precursor ion trap (4) during the period when the ion dissociation chamber (5) is operated for dissociation, isolation, discharge, etc. This configuration eliminates a decrease in permeability in the ion dissociation chamber (5), i.e., a decrease in throughput, which has been a problem in the ion dissociation chamber (5). This method enables structural analysis of a test sample to be conducted in an increased throughput.
