ABSTRACT:
An apparatus in which a current of air is directed across a surface of a substance of unknown identity to have molecules of the latter entrained therewith. The molecules are attracted electrostatically to the surface of a piezoelectric element to cause microscopic vibrations of the element. The microscopic vibrations result in the piezoelectric element emitting a minute voltage at a like frequency that is subsequently amplified. The amplified voltage is used to produce pulsed sound waves that are directed onto a resilient diaphram to vibrate the latter, and the mechanical energy of the diaphram being transferred to the piezoelectric element to amplify the voltage emitted. The amplified voltage is of sufficient magnitude to actuate an oscilloscope or recording computer to provide a distinctive pattern that is used to identify the unknown substance.
