A spray-jet molecular beam apparatus, which produces a molecular beam of neutral molecules in a vacuum from the sprayed mist of a sample solution, was previously developed. The apparatus was used in spectroscopic studies or as a means of molecular deposition. The spray-jet inlet system consisted of an ultrasonic nebulizer, an inlet chamber, and a pulsed nozzle. We report herein our experiments with alternative spray-jet inlet system that replaces the previous ultrasonic nebulizer with a pneumatic nebulizer. The efficiency of molecular beam generation was evaluated on the basis of the signal intensity of the multiphoton ionization time-of-flight mass spectra (MPI–TOFMS) for sample solutions and the amount of sample consumed. Introduction of the pneumatic spray-jet inlet system increased efficiency by a factor of 20 or more.
