Assignee: SHIMADZU CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 6:
7. A mass spectrometer, comprising:
an ionization section configured to generate ions from a sample;
a mass separation section configured to separate ions generated by the ionization section according to mass-to-charge ratio;
an ion detector configured to detect an ion separated by the mass separation section;
an ion capture section configured to capture an ion separated by the mass separation section;
an auxiliary measurement section configured to measure a physical quantity of the ion captured by the ion capture section, where the physical quantity is different from mass-to-charge ratio;
wherein the auxiliary measurement section includes:
an irradiation section configured to irradiate ions captured within the ion capture section with electromagnetic waves or a particle beam; and
a detection section configured to detect electromagnetic waves or a particle exiting from the ion capture section;
wherein the irradiation section is an electron-beam irradiation section configured to deliver an electron beam into the ion capture section; and
the detection section is configured to detect the electron beam diffracted by the ion;
a molecular structure candidate input reception section configured to receive an input of information of a molecular structure candidate; and
a first molecular structure estimation section configured to estimate a molecular structure of a molecule contained in a sample by comparing an electron diffraction image obtained by a measurement of the sample and an electron diffraction image prepared for the molecular structure candidate.
