Spray-Jet Technique for Studying Nonvolatile Functional Molecules: Toshiki Yamada, Hidenori Shinohara, Toshiya Kamikado, and Shinro Mashiko The spray-jet technique enables us to produce a molecular beam of non-volatile molecules under high vacuum from sprayed mists of sample solutions suspended in a carrier gas. A molecular beam apparatus and the spray-jet technique have been used together in spectroscopic studies and as a means of molecular beam deposition. During the process of developing the apparatus, we developed different spray-jet inlet systems. We compared these inlet systems in terms of the efficiency of molecular beam generation, which is evaluated by measuring the signal intensity of the multiphoton ionization time-of-flight mass spectrum (MPI|TOF MS) for a sample solution and the amount of sample consumed.
