Title:
MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2023/204187
Kind Code:
A1
Abstract:
A mass spectrometer according to one aspect of the present invention comprises: a LIT (4) that captures ions originating from a sample in a capture space stretching along a linear axis (100) and that emits some of the ions from the capture space to the outside; an ion guiding part (8) that receives the ions emitted from the LIT and delivers the ions to a subsequent stage, the ion guiding part (8) having an ion inlet through which the emitted ions are received, an ion outlet which transmits the received ions and/or ions produced from the received ions to a subsequent stage, and an ion passage route having a cross-sectional area that is reduced in conjunction with ions from the ion inlet advancing toward the ion outlet; a bunching part (5) that gathers ions emitted from the ion outlet of the ion guiding part to form an ion bunch, and transmits the ion bunch to the downstream side; and mass spectrometry units (6, 7) that, according to m/z, separate and detect ions contained in the ion bunch which has been formed and transmitted by the bunching part.
