Effect of buffer gas on the fluorescence yield of trapped gas-phase ions

Application Note


We investigated the dependence of three different gases, helium, argon, and nitrogen, on the fluorescence signal intensity of rhodamine 6G cations in the gas phase. The method is based on laser-induced fluorescence of ions trapped in a Fourier transform ion cyclotron mass spectrometer. We found that the use of helium results in the highest fluorescence signal, while no fluorescence was detected when using argon under the same conditions.
