The Stainless-Steel Propane Injector
Abstract
The stainless-steel injector is a compact, light-weight unit which operates on liquefied petroleum gas, eliminating the need of an air compressor; and the stainless-steel reduces the amount of corrosion attributable to acetic acid from bubbler samples. The unit includes the aspirator, a pressure regulator, gas filter, 0-30 psi gauge to indicate the jet pressure, and a 0-250 psi gauge for supply tank pressure. To determine the optimum jet and throat diameters, three different jets, and three different throats were made up; and the nine combinations were tested experimentally using a propane-butane mixture. A cross-section of the aspirator, and a drawing of the complete unit are given. The most promising use of the device is for sampling with impacting samplers for aerosols.
