なる。 Regarding the operation of the atomizing device according to this invention with the above configuration, the stopper 6 loosen and slide the pipe holder 4 in the direction of arrow A. In this case, when the viscosity of the sample liquid 8 is high, the distance between the tip 3a and the ejection hole 11 can be set to a maximum of 0.5 mm, and the flow rate of argon gas contained in the argon gas from the gas supply section 7a can be greatly increased. The sample gas increases to an appropriate concentration. Also, when the viscosity of the sample liquid 8 is low, the tip 3a and the jet hole 11
You can set the distance to a minimum of 0.1mm,
The flow rate of argon gas from the gas supply section 7a decreases, and the flow rate of argon gas contained in the sample gas exiting from the ejection hole 11 decreases, resulting in a sample gas with an appropriate concentration.
