Title:
ION SOURCE AND MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2021/124666
Kind Code:
A1
Abstract:
The present invention provides an ion source and a mass spectrometer that are capable of further reducing the dead volume in a connection part between a piping and a capillary. This ion source has a capillary and a piping. The capillary has a large diameter part forming a capillary upstream-side end surface on the upstream side. The large diameter part has a large diameter part downstream-side surface on the downstream side. The piping has a piping downstream-end surface on the downstream side. A capillary holding part has a hole through which the capillary upstream-side end surface can pass, and a surface on which the large diameter part downstream-side surface can be installed. The ion source is provided with a piping holding part that holds the piping. The capillary holding part and the piping holding part are arranged so that the capillary and the piping can be connected through contact between the capillary upstream-side end surface and the piping downstream-end surface.
