Abstract:
1. A probe comprising: a tubular liquid sample channel through which a liquid sample flows in a specified direction; a nebulizer gas channel through which a nebulizer gas flows in the specified direction, formed at the outer circumference of said liquid sample channel so as to have a round annular outer circumference and be coaxial with the liquid sample channel; a heating gas channel for injecting an assist gas in the specified direction, wherein a heating gas injection port is formed around the outlet end of said nebulizer gas channel so as to have a round annular outer circumference and be coaxial to the nebulizer gas channel; and a heating element which is arranged inside said heating gas channel and heats the assist gas for injecting through said heating gas injection port, an assist gas channel formed in all or part of the space between said nebulizer gas channel and heating gas channel, wherein an inlet channel connects to a main channel of said assist gas channel at a first point of said main channel and another portion of the main channel connects to said heating gas channel at a second point disposed further from said heating gas injection port than said first point with respect to the specified direction thereby causing the assist gas, prior to being heated by said heating element, to flow through the assist gas channel, and the assist gas after being heated by said heating element to flow through the heating gas channel.
