<p>A mass spectrometry method that makes it possible to perform high-sensitivity detection of a desorbed/ionized object substance to be measured in mass spectrometry in which the object substance to be measured is desorbed and ionized. The method includes placing at least an ionizing agent having two or more functional groups represented by Formula (1) below in a molecule:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ - (CF 2 ) COOH€ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein the ionizing agent has a boiling point of equal to or higher than 150°C and an object molecule to be measured on a substrate and irradiating the ionizing agent and the object molecule to be measured with a primary beam selected from ions, neutral particles, electrons, and a laser beam.</p> |
