Experiments to perform mass spectrometry with ion traps of submillimeter dimension are described. Several trap geometries amenable to microfabrication have been explored. In these experiments, vapor‐phase molecules were ionized by a pulse from a frequency‐quadrupled Nd:YAG laser. The ions were trapped and mass analyzed by manipulating the radiofrequency voltages on the trap electrodes. Effects of trapping parameters on mass resolution and sensitivity are discussed. © 1999 John Wiley & Sons, Ltd.
