Abstract:
A laser-cooled fluorescence mass spectrometry apparatus comprising:an ion trap for trapping sample ions, laser-cooled ions, and probe ions therein, the probe ions being different ions than the laser-cooled ions; first irradiating means for irradiating the sample ions, the laser-cooled ions, and the probe ions in the ion trap with a first laser beam for cooling the ions; second irradiating means for irradiating the sample ions, the laser-cooled ions, and the probe ions in the ion trap with a second laser beam for detecting temperature changes in the ions; detecting means for detecting the temperature changes in the ions; a first ion source for the sample ions; a second ion source for the laser-cooled ions; and a third ion source for the probe ions.
