PROBLEM TO BE SOLVED: To provide an inductively coupled plasma mass spectrometry method capable of suppressing generation of interfering ions interfering with an element to be analyzed even when introducing a sample having a solvent desolvated and vaporized by heating to perform mass spectrometry.SOLUTION: An inductively coupled plasma mass spectrometry method comprises the steps of: applying a high frequency to a plasma torch 2 running a carrier gas for carrying a sample having a solvent desolvated and vaporized by heating to light inductively coupled plasma; and performing mass spectrometry of the sample ionized by the inductively coupled plasma. The output of the high frequency is set to 700-850 W, and a flow rate of an auxiliary gas for passing through the periphery of the carrier gas to assist the lighting of the inductively coupled plasma is 1.1-1.5 L/min. |
