Patent ID: 11826770

Abstract:
To provide: an atomizer that allows a sample liquid to be made into minute droplets stably and that inhibits clogging of an aerosol gas outlet by salting out or the like when atomizing a sample containing a high density matrix; a sample introduction unit that includes the atomizer; and an analysis device. An atomizer includes: a liquid supply tube that has a first channel in which a liquid can circulate and that has, on one end, an outlet to spray the liquid; and a gas supply tube that encloses the liquid supply tube with a gap therebetween, that has a second channel in which a gas can circulate, and that has, on one end, an outlet to spray the gas. The second channel is defined by the outer circumferential face of the liquid supply tube and the inner circumferential face of the gas supply tube and has a narrow portion upstream of the outlet.
