Title:
SPRAY IONIZATION DEVICE, ANALYSIS DEVICE, AND SURFACE COATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/241098
Kind Code:
A1
Abstract:
Provided in the present disclosure is a spray ionization device comprising: a first tube (21) that has a first flow path (23) in which a liquid can flow, the first tube (21) having a first outlet (21a) on one end thereof from which the liquid is sprayed; a second tube (22) that surrounds the first tube (21) with a gap therebetween and has a second flow path (24) in which a gas can flow, the second tube (22) having a second outlet (22a) on the one end thereof and the second flow path (24) being defined by the outer peripheral surface (21c) of the first tube (21) and the inner peripheral surface (22b) of the second tube (22); and an electrode capable of contacting the liquid flowing through the first flow path (23), the electrode being able to apply a voltage to the liquid by means of a power source connected to the electrode, wherein, at the one end, the second outlet (22a) is disposed further toward a tip end than the first outlet (21a), at least part of the inner peripheral surface of the second tube (22) gradually narrows in diameter toward the second outlet (22a), the inner peripheral surface (22b) of the second outlet (22a) has a diameter equal to or greater than the diameter of the opening of the first outlet (21a), and charged droplets of the liquid can be sprayed from the second outlet (22a).
