Abstract
Provided is a technique to carry out mass spectrometry of a wide variety of subject compounds to be analyzed, each of which is extracted in a supercritical fluid. A mass spectrometer (1) includes: a supercritical fluid introduction section (3) for introducing and releasing, to vacuum, a supercritical fluid in which a subject compound for mass spectrometry is contained (extracted); an ionization section (4) that ionizes the subject compound which is extracted in the supercritical fluid, the ionization being carried out in the vacuum by a molecular reaction involving proton transfer; and a mass measurement section (5) that measures a mass of the subject compound which has been ionized.
Claims11
A mass spectrometer, comprising:
- a supercritical fluid introduction section that is provided for introducing and releasing, to vacuum, a supercritical fluid in which a subject compound for mass spectrometry is extracted and being held;
- an ionization section that ionizes the subject compound which is extracted and being held in the supercritical fluid, the ionization being carried out in the vacuum by a molecular reaction involving proton transfer;
- and
- a mass measurement section that measures a mass of the subject compound which has been ionized.
A mass spectrometric method, comprising the steps of:
- introducing and releasing, to vacuum, a supercritical fluid in which a subject compound for mass spectrometry is extracted;
- ionizing the subject compound, which is extracted and is being held in the supercritical fluid, the ionization being carried out in the vacuum by a molecular reaction involving proton transfer;
- and
- measuring a mass of the subject compound which has been ionized.
