Title:
LIQUID CHROMATOGRAPHY MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2019/049273
Kind Code:
A1
Abstract:
In the present invention, an inverted-L-shaped oven holder (3) is attached to a side surface of a housing (2a) of a mass spectrometer (2). A column oven (11) is attached to the top of a horizontal placement table of the oven holder (3). A straight tubular relay tube (25) that is connected to the capillary (23) of an ESI probe (22) within the mass spectrometer (2) using a joint protrudes to the outside of the housing (2a). The central axis of an outlet end part (110a) of a column (110) and the central axis of an inlet end part of the relay tube (25) are positioned on roughly the same straight line through the adjustment of the height of the placement table of the oven holder (3), and in a state where the openings of both end parts touch and oppose each other, the column oven (11) is shifted such that the two parts are connected. As a result, it is possible to send an eluate including a component separated by the column (110) to the capillary (23) via a very short relay tube (25), suppress component diffusion, and carry out highly sensitive analysis.
