Keywords:ion source, mass spectrometry, MEMS
A pulse-heating ion source has been established to peptides and proteins detection by only applying thermal energy from a single pulse without laser or high voltage. This study concerns the generation of negative ions of simple inorganic samples such as sodium chloride with the pulse-heating on-chip ionization source. As a result, peaks corresponding to OH- and Cl- signals were observed in the mass spectra indicating that the sodium chloride sample was successfully ionized by the system.22
