A pulse mode programmer has been developed for field desorption mass spectrometry that provides setting of the emitter heating current during the scans, switching off the emitter heating current during the intervals between consecutive scans and increasing it by 0.5 mA at the start of each scan. Using this heating device, the temperature dependence of field desorption mass spectra of some peptide synthesis products has been studied.
