Abstract
In the mass spectrometer system, a tip portion of a cylindrical portion (891) of a capillary (89) is coated with a coating material (892), the tip portion being an injection part for injecting a sample solution to an ionization section. Therefore, it is possible to suppress, by the coating material (892), the deformation of the capillary (89) when the sample solution is injected. In addition, it is possible to suppress the corrosion and the deformation of the capillary (89) by the coating material (892). As a result, the stability of the analysis operation in mass spectrometer system (1) can be improved.
Claims15
An ionizer for injecting a sample solution to an ionization section of a mass spectrometer to ionize the sample solution, the ionizer comprising
- a capillary having a tubular shape and a tip portion from which the sample solution passing through an inside of the capillary is injected,
- wherein
- at least a part of the tip portion of the capillary is coated with a coating material,
- a supercritical fluid containing a sample component is injected from the capillary as the sample solution,
- the capillary includes a side surface and a tip surface perpendicular to the side surface,
- the coating material covers a region including at least the tip surface of the capillary, and
- the coating material remains on the region including at least the tip surface of the capillary during injection of the supercritical fluid containing the sample component wherein the coating material covers only the tip surface of the capillary.
