A temperature dependent desorption process of molecular ions operating in field desorption mass spectrometry (FDMS) was examined by means of measurements of desorption rates using cholesterol, stearic acid, and poly(oxyethylene) nonylphenyl ether. The desorption of ions formed under high electric field followed the first order kinetics. The desorption rate constants were measured at several emitter currents, and apparent activation energies for the desorption of molecular ions were calculated. A mass transfer process operating in FDMS is discussed.
